Introduced DEV_TX_OFFLOAD_OUTER_UDP_CKSUM offload flags and PKT_TX_OUTER_TCP_CKSUM mbuf ol_flags to enable Tx outer UDP checksum offload.
PKT_TX_OUTER_UDP_CKSUM, not TCP
To use hardware Tx outer UDP checksum offload, the user needs to, - enable following in mbuff:
mbuf
a) fill outer_l2_len and outer_l3_len in mbuf b) set the PKT_TX_OUTER_UDP_CKSUM flag c) set the flag PKT_TX_OUTER_IPV4 or PKT_TX_OUTER_IPV6 - configure DEV_TX_OFFLOAD_OUTER_UDP_CKSUM offload flags in slow path Signed-off-by: Jerin Jacob <jerin.ja...@caviumnetworks.com>
The question about mbuf and ethdev changes separation is applicable here as well. I have no strong opinion, but I think it would be good to follow.
