Detailed Description

Packet IO capabilities.

Note that interface capabilities may differ between packet output modes. For example, LSO may not be supported in ODP_PKTOUT_MODE_TM mode, while it is supported in ODP_PKTOUT_MODE_DIRECT mode.

Examples: ipsec_api/odp_ipsec.c, odp_bench_pktio_sp.c, odp_classifier.c, odp_dmafwd.c, odp_ipsecfwd.c, odp_l2fwd.c, odp_l3fwd.c, odp_packet_dump.c, odp_packet_gen.c, odp_ping.c, odp_pktio_ordered.c, odp_sched_pktio.c, odp_switch.c, and odp_sysinfo.c.
