All,
We are using RX checksum offloading for L3 and L4 on the 82599 NIC. One odd behavior we have noticed is that UDP packets with a zero UDP checksum are being marked as invalid. The UDP checksum field for IPv4 + UDP is optional.
Is there a way to toggle the behavior? I have been reviewing the DataSheet and have not seen a way so far.
Thank you,
Bryan Benson
