| pkt | Packet handle |
| void* odp_packet_data | ( | odp_packet_t | pkt | ) |
Packet data pointer.
Returns pointer to the first byte of packet data. When packet is segmented, only a portion of packet data follows the pointer. When unsure, use e.g. odp_packet_seg_len() to check the data length following the pointer. Packet level offsets are calculated relative to this position.
When a packet is received from packet input, this points to the first byte of the received packet. Pool configuration parameters may be used to ensure that the first packet segment contains all/most of the data relevant to the application.
User can adjust the data pointer with e.g. push_head/pull_head (does not modify segmentation) and extend_head/trunc_head (may modify segmentation) calls.
| pkt | Packet handle |
| uint32_t odp_packet_seg_len | ( | odp_packet_t | pkt | ) |
Packet data length following the data pointer.
Returns number of data bytes (in the segment) following the current data pointer position. When unsure, use this function to check how many bytes can be accessed linearly after data pointer (odp_packet_data()). This equals to odp_packet_len() for single segment packets.

| void* odp_packet_push_head | ( | odp_packet_t | pkt, |
| uint32_t | len | ||
| ) |
Push out packet head.
Increase packet data length by moving packet head into packet headroom. Packet headroom is decreased with the same amount. The packet head may be pushed out up to 'headroom' bytes. Packet is not modified if there's not enough headroom space.
odp_packet_xxx: seg_len += len len += len headroom -= len data -= len
Operation does not modify packet segmentation or move data. Handles and pointers remain valid. User is responsible to update packet metadata offsets when needed.

Extend packet head.
Increase packet data length at packet head. Functionality is analogous to odp_packet_push_head() when data length is extended up to headroom size. When data length is increased more than that, new segments are added into the packet head and old segment handles become invalid.
A successful operation overwrites the packet handle with a new handle, which application must use as the reference to the packet instead of the old handle. Depending on the implementation, the old and new handles may be equal.
The operation return value indicates if any packet data or metadata (e.g. user_area) were moved in memory during the operation. If some memory areas were moved, application must use new packet/segment handles to update data pointers. Otherwise, all old pointers remain valid.
User is responsible to update packet metadata offsets when needed. Packet is not modified if operation fails.

A successful operation overwrites the packet handle with a new handle, which application must use as the reference to the packet instead of the old handle. Depending on the implementation, the old and new handles may be equal.
The operation return value indicates if any packet data or metadata (e.g. user_area) were moved in memory during the operation. If some memory areas were moved, application must use new packet/segment handles to update data pointers. Otherwise, all old pointers remain valid.
User is responsible to update packet metadata offsets when needed. Packet is not modified if operation fails.
| [in,out] | pkt | Pointer to packet handle. A successful operation outputs the new packet handle. |
| offset | Byte offset into the packet | |
| len | Number of bytes to add into the offset |
| 0 | Operation successful, old pointers remain valid |
| >0 | Operation successful, old pointers need to be updated |
| <0 | Operation failed |
| int odp_packet_rem_data | ( | odp_packet_t * | pkt, |
| uint32_t | offset, | ||
| uint32_t | len | ||
| ) |
Remove data from an offset.
Decrease packet data length by removing data area from the specified offset. The operation may modify packet segmentation and move data.
A successful operation overwrites the packet handle with a new handle, which application must use as the reference to the packet instead of the old handle. Depending on the implementation, the old and new handles may be equal.
The operation return value indicates if any packet data or metadata (e.g. user_area) were moved in memory during the operation. If some memory areas were moved, application must use new packet/segment handles to update data pointers. Otherwise, all old pointers remain valid.
User is responsible to update packet metadata offsets when needed. Packet is not modified if operation fails.

| offset | Byte offset into the packet | |
| len | Number of bytes to remove from the offset. When offset is zero: 0 ... packet_len - 1 bytes, otherwise 0 ... packet_len - offset bytes. |
| 0 | Operation successful, old pointers remain valid |
| >0 | Operation successful, old pointers need to be updated |
| <0 | Operation failed |
| int odp_packet_align | ( | odp_packet_t * | pkt, |
| uint32_t | offset, | ||
| uint32_t | len, | ||
| uint32_t | align | ||
| ) |
Align packet data.
Modify packet data alignment so that 'len' bytes between 'offset' and 'offset' plus 'len' are contiguous in memory and have a minimum alignment of 'align' bytes.
A successful operation overwrites the packet handle with a new handle, which the application must use as the reference to the packet instead of the old handle. Depending on the implementation, the old and new handles may be equal.
The operation return value indicates if any packet data outside of the requested area or metadata (e.g. user_area) were moved in memory during the operation. If some other memory areas were moved, application must use new packet/segment handles to update data pointers. Otherwise, old pointers remain valid.
Packet is not modified if operation fails.
| [in,out] | pkt | Pointer to packet handle. A successful operation outputs the new packet handle. |
| offset | Byte offset of the contiguous area | |
| len | Byte length of the contiguous area (0 ... packet_len) | |
| align | Minimum byte alignment of the contiguous area. Valid values are powers of 2. Use 0 to indicate no special alignment requirement. All implementations support alignments of up to at least 32 bytes. Request will fail if requested alignment exceeds implementation limits. |
| 0 | Operation successful, old pointers remain valid |
| >0 | Operation successful, old pointers need to be updated |
| <0 | Operation failed |
| int odp_packet_is_segmented | ( | odp_packet_t | pkt | ) |

A packet has always the last segment (has at least one segment).
| pkt | Packet handle |
| odp_packet_seg_t odp_packet_next_seg | ( | odp_packet_t | pkt, |
| odp_packet_seg_t | seg | ||
| ) |

Returns handle to the next segment after the current segment, or ODP_PACKET_SEG_INVALID if there are no more segments. Use odp_packet_first_seg() to get handle to the first segment.
| pkt | Packet handle |
| seg | Current segment handle |
| ODP_PACKET_SEG_INVALID | if there are no more segments |

Returns segment data length in bytes.
| pkt | Packet handle |
| seg | Segment handle |
| int odp_packet_concat | ( | odp_packet_t * | dst, |
| odp_packet_t | src | ||
| ) |
Concatenate two packets.
Concatenate all packet data from 'src' packet into tail of 'dst' packet. Operation preserves 'dst' packet metadata in the resulting packet, while 'src' packet handle, metadata and old segment handles for both packets become invalid. Source and destination packet handles must not refer to the same packet.
A successful operation overwrites 'dst' packet handle with a new handle, which application must use as the reference to the resulting packet instead of the old handle. Depending on the implementation, the old and new handles may be equal.
The operation return value indicates if any packet data or metadata (e.g. user_area) were moved in memory during the operation. If some memory areas were moved, application must use new packet/segment handles to update data pointers. Otherwise, all old pointers remain valid.
The resulting packet is always allocated from the same pool as the destination packet. The source packet may have been allocated from any pool.
On failure, both handles remain valid and packets are not modified.
| [in,out] | dst | Pointer to destination packet handle. A successful operation outputs the new packet handle. |
| src | Source packet handle |
| 0 | Operation successful, old pointers remain valid |
| >0 | Operation successful, old pointers need to be updated |
| <0 | Operation failed |
| int odp_packet_split | ( | odp_packet_t * | pkt, |
| uint32_t | len, | ||
| odp_packet_t * | tail | ||
| ) |
Split packet into two packets.
Split the packet after 'len' bytes. The first 'len' bytes of data and metadata remain in the head packet. A successful operation outputs a handle for the tail packet and overwrites 'pkt' packet handle with a new handle, which application must use as the reference to the resulting head packet. Depending on the implementation, the old and new 'pkt' handles may be equal.
The operation return value indicates if any packet data or metadata (e.g. user_area) were moved in memory during the operation. If some memory areas were moved, application must use new packet/segment handles to update data pointers. Otherwise, all old pointers remain valid.
The tail packet holds the rest of the data (odp_packet_len() - 'len' bytes). The packet is allocated from the same pool as the original packet and metadata is initialized with default values.
For performance reasons (zero copy), the head packet may have zero tailroom and the tail packet may have zero headroom length after the operation. Both packets may be extended normally.
The original packet is not modified on failure.
| [in,out] | pkt | Pointer to packet handle. A successful operation outputs a new packet handle for the head packet. |
| len | Data length remaining in the head packet (1 ... packet_len - 1) | |
| tail | Pointer to output the tail packet handle |
| 0 | Operation successful, old pointers remain valid |
| >0 | Operation successful, old pointers need to be updated |
| <0 | Operation failed |
| void* odp_packet_buf_head | ( | odp_packet_buf_t | pkt_buf | ) |
Packet buffer head pointer.
Packet buffer start address. Buffer level headroom starts from here. For the first packet buffer of a packet this is equivalent to odp_packet_head().
| pkt_buf | Packet buffer |
| uint32_t odp_packet_buf_size | ( | odp_packet_buf_t | pkt_buf | ) |
Packet buffer size in bytes.
Packet buffer size is calculated from the buffer head pointer (see odp_packet_buf_head()). It contains all buffer level headroom, data, and tailroom. For a single segmented packet this is equivalent to odp_packet_buf_len().
| pkt_buf | Packet buffer |
| uint32_t odp_packet_buf_data_offset | ( | odp_packet_buf_t | pkt_buf | ) |
Packet buffer data offset.
Offset from the buffer head pointer to the first byte of packet data in the packet buffer. Valid values range from 0 to buf_size - 1. For the first packet buffer of a packet this is equivalent to odp_packet_headroom().
| pkt_buf | Packet buffer |
| uint32_t odp_packet_buf_data_len | ( | odp_packet_buf_t | pkt_buf | ) |
Packet buffer data length in bytes.
Packet buffer contains this many bytes of packet data. Valid values range from 1 to buf_size - data_offset. For the first packet buffer of a packet this is equivalent to odp_packet_seg_len().
| pkt_buf | Packet buffer |
| void odp_packet_buf_data_set | ( | odp_packet_buf_t | pkt_buf, |
| uint32_t | data_offset, | ||
| uint32_t | data_len | ||
| ) |

| data_len | Packet buffer data length in bytes |
| odp_packet_buf_t odp_packet_buf_from_head | ( | odp_pool_t | pool, |
| void * | head | ||
| ) |
Convert packet buffer head pointer to handle.
Converts a packet buffer head pointer (from a previous odp_packet_buf_head() call) to a packet buffer handle. This allows an application to save memory as it can store only buffer pointers (instead of pointers and handles) and convert those to handles when needed. This conversion may be done only for packet buffers that are not part of any packet (i.e. buffers between odp_packet_disassemble() and odp_packet_reassemble() calls).
This call can be used only for packets of an external memory pool (see odp_pool_ext_create()).
| pool | Pool from which the packet buffer (disassembled packet) originate from |
| head | Head pointer |
| ODP_PACKET_BUF_INVALID | on failure |
| uint32_t odp_packet_disassemble | ( | odp_packet_t | pkt, |
| odp_packet_buf_t | pkt_buf[], | ||
| uint32_t | num | ||
| ) |
Disassemble packet into packet buffers.
Breaks up a packet into a list of packet buffers. Outputs a packet buffer handle for each segment of the packet (see odp_packet_num_segs()). After a successful operation the packet handle must not be referenced anymore. Packet buffers are reassembled into a new packet (or several new packets) with a later odp_packet_reassemble() call(s). All packet buffers must be reassembled into a packet and freed into the originating pool before the pool is destroyed.
This call can be used only for packets of an external memory pool (see odp_pool_ext_create()).
| pkt | Packet to be disassembled | |
| [out] | pkt_buf | Packet buffer handle array for output |
| num | Number of elements in packet buffer handle array. Must be equal to or larger than number of segments in the packet. |
| 0 | on failure |
| odp_packet_t odp_packet_reassemble | ( | odp_pool_t | pool, |
| odp_packet_buf_t | pkt_buf[], | ||
| uint32_t | num | ||
| ) |
Reassemble packet from packet buffers.
Forms a new packet from packet buffers of a previous odp_packet_disassemble() call(s). Packet buffers from different disassembled packets may be used, but all buffers must be from packets of the same pool. Packet pool capability 'max_segs_per_pkt' defines the maximum number of packet buffers that can be reassembled to form a new packet.
Application may use odp_packet_buf_data_set() to adjust data_offset and data_len values in each packet buffer to match the current packet data placement. The operation maintains packet data content and position. Each buffer becomes a segment in the new packet. Packet metadata related to data length and position are set according data layout in the buffers. All other packet metadata are set to their default values. After a successful operation packet buffer handles must not be referenced anymore.
This call can be used only for packets of an external memory pool (see odp_pool_ext_create()).
| pool | Pool from which all packet buffers (disassembled packets) originate from |
| pkt_buf | Packet buffers to form a new packet |
| num | Number of packet buffers. Must not exceed max_segs_per_pkt pool capability. |
| ODP_PACKET_INVALID | on failure |
| odp_packet_t odp_packet_ref_static | ( | odp_packet_t | pkt | ) |
Create a static reference to a packet.
A static reference is used to obtain an additional handle for referring to the entire packet as it is. As long as a packet has multiple (static) references, any of the references (including 'pkt') must not be used to modify the packet in any way - both data and metadata must remain static. The packet may be modified again when there is a single reference left. Static and dynamic references must not be mixed. Results are undefined if these restrictions are not observed.
While static references are inflexible they offer efficient way to do, e.g., packet retransmissions. Use odp_packet_ref() or odp_packet_ref_pkt() for more flexible, dynamic references.
Packet is not modified on failure.
| pkt | Handle of the packet for which a static reference is to be created. |
| ODP_PACKET_INVALID | On failure |
| odp_packet_t odp_packet_ref | ( | odp_packet_t | pkt, |
| uint32_t | offset | ||
| ) |
Create a reference to a packet.
Returns a new (dynamic) reference to a packet starting the shared part of the data at a specified byte offset. Metadata and data before the offset are not shared with other references of the packet. The rest of the data is shared and must be treated as read only. Initially the returned reference has metadata initialized to default values and does not contain unshared data. Packet (head) manipulation functions may be used normally to, e.g., add a unique header onto the shared payload. The shared part of the packet may be modified again when there is a single reference left. Static and dynamic references must not be mixed. Results are undefined if these restrictions are not observed.
The packet handle 'pkt' may itself be a (dynamic) reference to a packet.
If the caller does not intend to modify either the packet or the new reference to it, odp_packet_ref_static() may be used to create a static reference that is more optimized for that use case.
Packet is not modified on failure.
| pkt | Handle of the packet for which a reference is to be created. |
| offset | Byte offset in the packet at which the shared part is to begin. This must be in the range 0 ... odp_packet_len(pkt)-1. |
| ODP_PACKET_INVALID | On failure |
| odp_packet_t odp_packet_ref_pkt | ( | odp_packet_t | pkt, |
| uint32_t | offset, | ||
| odp_packet_t | hdr | ||
| ) |
Create a reference to a packet with a header packet.
This operation is otherwise identical to odp_packet_ref(), but it prepends a supplied 'hdr' packet as the head of the new reference. The resulting packet consists metadata and data of the 'hdr' packet, followed by the shared part of packet 'pkt'.
The packet handle ('pkt') may itself be a (dynamic) reference to a packet, but the header packet handle ('hdr') must be unique. Both packets must be have been allocated from the same pool and the handles must not refer to the same packet. Results are undefined if these restrictions are not observed.
Packets are not modified on failure. The header packet 'hdr' is consumed on success.
| pkt | Handle of the packet for which a reference is to be created. |
| offset | Byte offset in 'pkt' at which the shared part is to begin. Must be in the range 0 ... odp_packet_len(pkt)-1. |
| hdr | Handle of the header packet to be prefixed onto the new reference. Must be a unique reference. |
| ODP_PACKET_INVALID | On failure |
| int odp_packet_has_ref | ( | odp_packet_t | pkt | ) |
Test if packet has multiple references.
A packet that has multiple references share data with other packets. In case of a static reference it also shares metadata. Shared parts must be treated as read only.
New references are created with odp_packet_ref_static(), odp_packet_ref() and odp_packet_ref_pkt() calls. The intent of multiple references is to avoid packet copies, however some implementations may do a packet copy for some of the calls. If a copy is done, the new reference is actually a new, unique packet and this function returns '0' for it. When a real reference is created (instead of a copy), this function returns '1' for both packets (the original packet and the new reference).
| pkt | Packet handle |
| 0 | This is the single reference to the packet |
| 1 | Packet has multiple references |
| odp_packet_t odp_packet_copy | ( | odp_packet_t | pkt, |
| odp_pool_t | pool | ||

| uint32_t | len, | ||
| odp_pool_t | pool | ||
| ) |
Partial copy of a packet.
Copy 'len' bytes of data starting from 'offset' into a new packet. Metadata in the new packet is initialized with default values. Maximum number of bytes to copy is packet data length minus the offset. The pool must be a packet pool.

| uint32_t | src_offset, | ||
| uint32_t | len | ||
| ) |
Copy data from another packet.
Copy 'len' bytes of data from 'src' packet to 'dst' packet. Copy starts from the specified source and destination packet offsets. Copied areas (offset ... offset + len) must not exceed their packet data lengths. Source and destination packet handles must not refer to the same packet (use odp_packet_copy_data() or odp_packet_move_data() for a single packet).
Packet is not modified on an error.

| uint32_t | src_offset, | ||
| uint32_t | len | ||
| ) |
Move data within packet.
Copy 'len' bytes of data from 'src_offset' to 'dst_offset'. Copied areas (offset ... offset + len) may overlap by any number of bytes, but must not exceed packet data length. When areas overlap, copying takes place as if source bytes are first copied into a temporary buffer, and then from there to the destination. Packet is not modified on an error.
| pkt | Packet handle |

| src_offset | Source byte offset |
| len | Number of bytes to move |

| int odp_packet_parse | ( | odp_packet_t | pkt, |
| uint32_t | offset, | ||
| const odp_packet_parse_param_t * | param | ||
| ) |
Parse packet.
Parse protocol headers in packet data and update layer/protocol specific metadata (e.g. offsets, errors, protocols, checksum statuses, etc). Parsing starts at 'offset', which is the first header byte of protocol 'param.proto'. Parameter 'param.last_layer' defines the last layer application requests to check. Use ODP_PROTO_LAYER_ALL for all layers. A successful operation sets (or resets) packet metadata for all layers from the layer of 'param.proto' to the application defined last layer. In addition, offset (and pointer) to the next layer is set. Other layer/protocol specific metadata have undefined values. When operation fails, all layer/protocol specific metadata have undefined values.

| int | num, | ||
| const odp_packet_parse_param_t * | param | ||

| pkt | Packet handle array |
| offset | Byte offsets into the packets |
| num | Number of packets and offsets |
| param | Parse parameters. Proto and last_layer fields must be set. Clear all check bits that are not used. |

| odp_packet_parse_result_t * | result | ||
| ) |
Read parse results.
Read out the most commonly used packet parse results. The same information is available through individual function calls, but this call may be more efficient when reading multiple results from a packet.
| pkt | Packet handle | |

| ODP_PKTIO_INVALID | Packet was not received on any interface |
| void odp_packet_input_set | ( | odp_packet_t | pkt, |
| odp_pktio_t | pktio | ||
| ) |
Set packet input interface.
Set packet input interface to a valid packet IO handle or ODP_PKTIO_INVALID. An application may use this for testing or other purposes, when perception of the packet input interface need to be changed. The call updates both input interface handle (odp_packet_input()) and index (odp_packet_input_index()).
| pkt | Packet handle |
| pktio | Handle to a valid packet input interface or ODP_PKTIO_INVALID. ODP_PKTIO_INVALID indicates that the packet was not received by any packet IO interface. |
| int odp_packet_input_index | ( | odp_packet_t | pkt | ) |
Packet input interface index.
Returns the index of the packet I/O interface that received the packet, or <0 when the packet was allocated/reset by the application.
| pkt | Packet handle |
| <0 | Packet was not received on any interface |
| void* odp_packet_user_ptr | ( | odp_packet_t | pkt | ) |
User context pointer.
Return previously stored user context pointer. If not otherwise documented, the pointer value is maintained over packet manipulating operations. Implementation initializes the pointer value to NULL during new packet creation (e.g. alloc and packet input) and reset.
| pkt | Packet handle |
| void odp_packet_user_ptr_set | ( | odp_packet_t | pkt, |
| const void * | user_ptr | ||
| ) |
Set user context pointer.
Each packet has room for a user defined context pointer. The pointer value does not necessarily represent a valid address - e.g. user may store any value of type intptr_t. ODP may use the pointer for data prefetching, but must ignore any invalid addresses.
| pkt | Packet handle |
| user_ptr | User context pointer |
| void* odp_packet_user_area | ( | odp_packet_t | pkt | ) |
User area address.
Each packet has an area for user data. Size of the area is fixed and defined in packet pool parameters.

User area size.
The size is fixed and defined in packet pool parameters.
| pkt | Packet handle |
| int odp_packet_user_flag | ( | odp_packet_t | pkt | ) |
Check user flag.
Implementation clears user flag during new packet creation (e.g. alloc and packet input) and reset. User may set the flag with odp_packet_user_flag_set(). Implementation never sets the flag, only clears it. The flag may be useful e.g. to mark when the user area content is valid.
| pkt | Packet handle |
| 0 | User flag is clear |
| >0 | User flag is set |
| void odp_packet_user_flag_set | ( | odp_packet_t | pkt, |

| NULL | Layer 2 offset has not been set |
| uint32_t odp_packet_l2_offset | ( | odp_packet_t | pkt | ) |
Layer 2 start offset.
Returns offset to the start of layer 2. The offset is calculated from the current odp_packet_data() position in bytes. Packet parsing sets the offset according to parse configuration and layers recognized in the packet. Data start position updating functions (e.g. odp_packet_push_head()) do not modify the offset, but user sets a new value when needed.
| pkt | Packet handle |
| ODP_PACKET_OFFSET_INVALID | Layer 2 offset has not been set |
| int odp_packet_l2_offset_set | ( | odp_packet_t | pkt, |
| uint32_t | offset | ||

| odp_packet_chksum_status_t odp_packet_l3_chksum_status | ( | odp_packet_t | pkt | ) |
Layer 3 checksum check status.
Returns the result of the latest layer 3 checksum check done for the packet. The status tells if checksum check was attempted and the result of the attempt. It depends on packet input (or IPSEC) configuration, packet content and implementation capabilities if checksum check is attempted for a packet.
| pkt | Packet handle |
| odp_packet_chksum_status_t odp_packet_l4_chksum_status | ( | odp_packet_t | pkt | ) |
Layer 4 checksum check status.
Returns the result of the latest layer 4 checksum check done for the packet. The status tells if checksum check was attempted and the result of the attempt. It depends on packet input (or IPSEC) configuration, packet content and implementation capabilities if checksum check is attempted for a packet.
When a UDP packet does not have a checksum (e.g. checksum field of a UDP/IPv4 packet is zero), checksum check result is ODP_PACKET_CHKSUM_OK.
| pkt | Packet handle |
| void odp_packet_l3_chksum_insert | ( | odp_packet_t | pkt, |
| int | insert | ||
| ) |
Layer 3 checksum insertion override.
Override checksum insertion configuration per packet. This per packet setting overrides a higher level configuration for checksum insertion into a L3 header during packet output processing.
Calling this function is always allowed but the checksum will not be inserted if the packet is output through a pktio that does not have the relevant checksum insertion enabled.
L3 type and L3 offset in packet metadata should provide valid protocol and header offset for checksum insertion purposes.
| pkt | Packet handle |

| odp_packet_data_range_t * | range | ||
| ) |
Ones' complement sum of packet data.
Returns 16-bit ones' complement sum that was calculated over a portion of packet data during a packet processing operation (e.g. packet input or IPSEC offload). The data range is output with 'range' parameter, and usually includes IP payload (L4 headers and payload). When 'range.length' is zero, the sum has not been calculated. In case of odd number of bytes, calculation uses a zero byte as padding at the end. The sum may be used as part of e.g. UDP/TCP checksum checking, especially with IP fragments.
| pkt | Packet handle | |
| [out] | range | Data range of the sum (output). The calculation started from range.offset and included range.length bytes. When range.length is zero, the sum has not been calculated. |
| uint32_t odp_packet_flow_hash | ( | odp_packet_t | pkt | ) |

| pkt | Packet handle |
| flow_hash | Hash value to set |
| odp_time_t odp_packet_ts | ( | odp_packet_t | pkt | ) |
Packet timestamp.
Returns timestamp value recorded into the packet. Use odp_packet_has_ts() to check if the packet has a valid timestamp. Packet input uses packet IO interface specific time source and thus timestamp (or nanosecond) values from one interface cannot be mixed with values from another interface (or time source in general). Packet IO interface timestamp resolution can be checked with odp_pktio_ts_res() and current time with odp_pktio_time().
Time API operations (e.g. odp_time_diff()) can be used with packet timestamp values or when converting those into nanoseconds (odp_time_to_ns()).
| pkt | Packet handle |
| void odp_packet_ts_set | ( | odp_packet_t | pkt, |
| odp_time_t | timestamp | ||

| const odp_packet_lso_opt_t * | lso_opt | ||
| ) |
Request Large Send Offload (LSO) for a packet.
Setup packet metadata which requests LSO segmentation to be performed during packet output. The selected LSO profile specifies details of the segmentation operation to be done. Depending on LSO profile options, additional metadata (e.g. L3/L4 protocol header offsets) may need to be set on the packet.
| pkt | Packet handle |
| lso_opt | LSO options |
| 0 | On success |
| <0 | On failure |
| void odp_packet_lso_request_clr | ( | odp_packet_t | pkt | ) |

| uint32_t odp_packet_payload_offset | ( | odp_packet_t | pkt | ) |
Payload data offset.
Returns offset to the start of payload data. Packet data before this offset is considered as protocol headers. The offset is calculated from the current odp_packet_data() position in bytes. Data start position updating functions (e.g. odp_packet_push_head()) do not modify the offset, but user sets a new value when needed.
Packet parsing does not set this offset. Initial offset value is undefined. Application may utilize the offset for internal purposes or when requesting LSO segmentation for the packet.
| pkt | Packet handle |
| ODP_PACKET_OFFSET_INVALID | Payload data offset has not been set |
| int odp_packet_payload_offset_set | ( | odp_packet_t | pkt, |
| uint32_t | offset | ||

| uint64_t | tmo_ns | ||
| ) |
Enable or disable Tx packet aging.
Enable or disable Tx packet drop based on packet age. When enabled, packet will be dropped if it is in Tx pktout queue or traffic shapers/schedulers for longer than timeout set.
When tmo_ns is !0: Aging is enabled 0: Aging is disabled
Aging is disabled by default. Maximum tmo value is defined by max_tx_aging_tmo_ns capa.

| 0 | If Aging drop is disabled. |
| int odp_packet_tx_compl_request | ( | odp_packet_t | pkt, |
| const odp_packet_tx_compl_opt_t * | opt | ||
| ) |
Request packet transmit completion.
Enables or disables packet transmit completion request for the packet. Completion may be requested either in event (ODP_PACKET_TX_COMPL_EVENT) or poll (ODP_PACKET_TX_COMPL_POLL) mode. When event mode is enabled, an event of type ODP_EVENT_PACKET_TX_COMPL will be sent to the destination queue to signal transmit completion. When poll mode is enabled, odp_packet_tx_compl_done() is used with the provided completion identifier to check the completion. In both cases, transmit completion is reported only after pktio interface has finished processing the packet.
A previously enabled request can be disabled by setting the mode to ODP_PACKET_TX_COMPL_DISABLED. Transmit completion request is disabled by default.
| pkt | Packet handle |
| opt | Packet transmit completion request options |
| 0 | On success |
| <0 | On failure |
| int odp_packet_has_tx_compl_request | ( | odp_packet_t | pkt | ) |

| void odp_packet_free_ctrl_set | ( | odp_packet_t | pkt, |
| odp_packet_free_ctrl_t | ctrl | ||
| ) |
Set packet free control option.
This option enables application to control if a packet is freed/not freed back into a pool after an ODP offload feature has finished processing it. The option does not have an effect on odp_packet_free() or other direct free calls. It affects only packets that are sent directly through a packet output interface queue (odp_pktout_queue_t or odp_queue_t), also when packets are LSO offloaded. Packets transmitted through inline IPsec or TM are not affected.
Packet output interface frees transmitted packets by default. When the option is set to ODP_PACKET_FREE_CTRL_DONT_FREE, packet output will not free the packet after transmit and application may reuse or free the packet as soon as its transmission is complete (see e.g. odp_packet_tx_compl_done()). Check packet IO interface capability free_ctrl.dont_free (odp_pktio_capability_t.free_ctrl) for the option support. When an interface does not support the option, it ignores the value.
The option must not be enabled on packets that have multiple references. The default value is ODP_PACKET_FREE_CTRL_DISABLED.
| pkt | Packet handle |
| ctrl | Packet free control option value |
| odp_packet_free_ctrl_t odp_packet_free_ctrl | ( | odp_packet_t | pkt | ) |

| void odp_packet_proto_stats_request | ( | odp_packet_t | pkt, |
| odp_packet_proto_stats_opt_t * | opt | ||
| ) |
Request packet proto stats.
The statistics enabled in the proto stats object are updated for the packet in packet output when the packet is transmitted or dropped. The statistics update is done as the last step of output processing after possible packet transformations (e.g. fragmentation, IPsec) that may occur. If a packet is fragmented or segmented to multiple packets as part of output processing, all the resulting packets inherit the proto stats object association from the original packet.
The relevant octet counts will be updated with the actual packet length at the time of transmission or drop plus the respective adjustment value passed in the 'opt' parameter. The octet counts thus include possible additional headers added by ODP during packet output (e.g. ESP header added by inline outbound IPsec processing). Ethernet padding and FCS are not included in the octet counts. The adjustment value is added only if the respective capability field is true and otherwise ignored.
| pkt | Packet handle |
| opt | Proto stats options. If NULL, then proto stats update is disabled for this packet. |
