Field Documentation

◆ max_profiles

uint32_t odp_lso_capability_t::max_profiles

Maximum number of LSO profiles.

When zero, LSO is not supported.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 919 of file api/spec/packet_io_types.h.

◆ max_profiles_per_pktio

uint32_t odp_lso_capability_t::max_profiles_per_pktio

Maximum number of LSO profiles per packet IO interface.

When zero, LSO is not supported by the interface.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 923 of file api/spec/packet_io_types.h.

◆ max_packet_segments

uint32_t odp_lso_capability_t::max_packet_segments

Maximum number of segments in an input packet.

When one, LSO operation accepts only non-segmented packets as input.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 927 of file api/spec/packet_io_types.h.

◆ max_segments

uint32_t odp_lso_capability_t::max_segments

Maximum number of segments an LSO operation may create.

This implies that the maximum supported input packet payload size for an LSO operation is max_segments * max_payload_len bytes.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 932 of file api/spec/packet_io_types.h.

◆ max_payload_len

uint32_t odp_lso_capability_t::max_payload_len

Maximum payload length per an LSO generated packet (in bytes).

This is the maximum value for max_payload_len in odp_packet_lso_opt_t.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 936 of file api/spec/packet_io_types.h.

◆ max_payload_offset

uint32_t odp_lso_capability_t::max_payload_offset

Maximum supported offset to the packet payload (in bytes).

This is the maximum value for payload_offset in odp_packet_lso_opt_t.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 940 of file api/spec/packet_io_types.h.

◆ add_segment_num

uint16_t odp_lso_capability_t::add_segment_num

ODP_LSO_ADD_SEGMENT_NUM support.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 945 of file api/spec/packet_io_types.h.

◆ add_payload_len

uint16_t odp_lso_capability_t::add_payload_len

ODP_LSO_ADD_PAYLOAD_LEN support.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 948 of file api/spec/packet_io_types.h.

◆ add_payload_offset

uint16_t odp_lso_capability_t::add_payload_offset

ODP_LSO_ADD_PAYLOAD_OFFSET support.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 951 of file api/spec/packet_io_types.h.

◆ write_bits

uint16_t odp_lso_capability_t::write_bits

ODP_LSO_WRITE_BITS support.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 954 of file api/spec/packet_io_types.h.

◆ max_num_custom

uint8_t odp_lso_capability_t::max_num_custom

Maximum number of custom fields supported per LSO profile.

When zero, custom fields are not supported.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 960 of file api/spec/packet_io_types.h.

◆ custom

uint32_t odp_lso_capability_t::custom

ODP_LSO_PROTO_CUSTOM support.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 965 of file api/spec/packet_io_types.h.

◆ ipv4

uint32_t odp_lso_capability_t::ipv4

ODP_LSO_PROTO_IPV4 support.

Examples: odp_packet_gen.c, and odp_sysinfo.c.

Definition at line 968 of file api/spec/packet_io_types.h.

◆ ipv6

uint32_t odp_lso_capability_t::ipv6

ODP_LSO_PROTO_IPV6 support.
