In this case, the proper value is PKT_RX_IP_CKSUM_BAD. PKT_RX_IP_CKSUM_NONE means that the checksum may be incorrect in the packet headers, but the integrity of the IP header is verified. This is mostly useful for virtual drivers. Fixes: 7ec39d8c524b ("net/bnxt: update status of Rx IP/L4 CKSUM") Cc: stable@dpdk.org Signed-off-by: Olivier Matz --- Hi Ajit, PKT_RX_IP_CKSUM_UNKNOWN is also a good candidate instead of PKT_RX_IP_CKSUM_BAD. Please can you check?
