[dpdk-dev] ixgbe and UDP with zero checksum

Hi, performing some tests, I noticed that on ixgbe when receiving UDP packets with zero checksum (no checksum) over IPv4, the corresponding ol_flag for the l4 checksum is set to PKT_RX_L4_CKSUM_BAD. In particular, this apparently has an impact on OvS using ct() action where UDP packets with zero
