Use atomic instead of internal in_errors counter in loop and pcap so that these counters are handled the same way in every pktio. Signed-off-by: Jere Leppänen <jere.leppanen@nokia.com> Reviewed-by: Tuomas Taipale <tuomas.taipale@nokia.com> Reviewed-by: Matias Elo <matias.elo@nokia.com>
2022-06-21linux-gen: pktio: increment in_discards when packet cannot be classifiedJere Leppänen
When classification is enabled, but packet doesn't match any CoS and default CoS is not set, or packet has an error and error CoS is not set, the packet is dropped. In this case, increment in_discards counter. Also, fit existing in_discards increment calls on one line.

2022-05-27linux-gen: pktio: validate L4 checksum in _odp_packet_parse_common()Jere Leppänen
We've been avoiding L4 checksum validation in case the packet is dropped due to other parse errors or classification. However, L4 checksum must be validated before classification, otherwise packets with an invalid checksum are not classified to the error CoS. Move L4 checksum validation into _odp_packet_parse_common().

2022-05-27linux-gen: pktio: use stats_extra.in_discards instead of stats.in_discardsJere Leppänen
When unable to copy a packet, use stats_extra.in_discards instead of stats.in_discards. In many pktios (although not loop or pcap), the latter comes directly from e.g. a socket. The former is therefore more suitable for other errors.
