Field Documentation

lso_proto

odp_lso_protocol_t odp_lso_profile_param_t::lso_proto

Segmentation protocol.

Selects on which protocol LSO operation performs segmentation (e.g. IP fragmentation vs. TCP segmentation). When ODP_LSO_PROTO_CUSTOM is selected, only custom field modifications are performed. The default value is ODP_LSO_PROTO_NONE. Check LSO capability for supported protocols.

Definition at line 1095 of file api/spec/packet_io_types.h.

mod_op

odp_lso_modify_t odp_lso_profile_param_t::mod_op

Field modify operation.

Selects how value of the field is modified from its original value during segmentation. Field value is assumed to be in network (big endian) byte order.

Definition at line 1109 of file api/spec/packet_io_types.h.

size

uint8_t odp_lso_profile_param_t::size

Field size in bytes.

Valid values are 1, 2, 4, and 8 bytes.

Definition at line 1115 of file api/spec/packet_io_types.h.

num_custom

uint8_t odp_lso_profile_param_t::num_custom

Number of custom fields specified.

The default value is 0.

Definition at line 1120 of file api/spec/packet_io_types.h.

struct { ... } odp_lso_profile_param_t::custom

Custom fields.

Set lso_proto to ODP_LSO_PROTO_CUSTOM when using custom fields. Fields are defined in the same order they appear in the packet.
