I suspect this is actually caused by csum issue in TX side: on RX,
socket pktio does not validate csum (and accept the packets) but on
dpdk pktio the csum is validated and packets are dropped.
I am not seeing this in my setup because default txq_flags for igb
driver (1G interface) is
.txq_flags = 0
while for ixgbe (10G interface) is:
.txq_flags = ETH_TXQ_FLAGS_NOMULTSEGS |
ETH_TXQ_FLAGS_NOOFFLOADS,
/B
