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_sysinfo.c.

Definition at line 826 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_sysinfo.c.

Definition at line 830 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_sysinfo.c.

Definition at line 834 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_sysinfo.c.

Definition at line 839 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_sysinfo.c.

Definition at line 843 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_sysinfo.c.

Definition at line 847 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_sysinfo.c.

Definition at line 864 of file api/spec/packet_io_types.h.
