Detailed Description

Packet input configuration options bit field.

Packet input configuration options listed in a bit field structure. Packet input timestamping may be enabled for all packets or at least for those that belong to time synchronization protocol (PTP).

Packet input checksum checking may be enabled or disabled. When it is enabled, implementation will attempt to verify checksum correctness on incoming packets and depending on drop configuration either deliver erroneous packets with appropriate flags set (e.g. odp_packet_has_l3_error(), odp_packet_l3_chksum_status()) or drop those. When packet dropping is enabled, application will never receive a packet with the specified error and may avoid to check the error flag.

If checksum checking is enabled, IPv4 header checksum checking is always done for packets that do not have IP options and L4 checksum checking is done for unfragmented packets that do not have IPv4 options or IPv6 extension headers. In other cases checksum checking may or may not be done. For example, L4 checksum of fragmented packets is typically not checked.

IPv4 checksum checking may be enabled only when parsing level is ODP_PROTO_LAYER_L3 or higher. Similarly, L4 level checksum checking may be enabled only with parsing level ODP_PROTO_LAYER_L4 or higher.

Whether checksum checking was done and whether a checksum was correct can be queried for each received packet with odp_packet_l3_chksum_status() and odp_packet_l4_chksum_status().
