[dpdk-dev] ixgbe tcp cksum offload

Hi, I am trying to use ixgbe tcp cksum h/w offload by following steps: - populate pseudo cksum - set l2_len, l3_len, l4_len - set ol_flags But I found the pkt doesn't get right h/w checksum by sniffing on recv side, and TCP cksum still leave with the original pseudo cksum. And I verified thos
