Subject: [dpdk-dev] 82599 Checksum offloading for UDP
Date: Thu, 21 Nov 2013 18:06:47 +0000 [thread overview]
Message-ID: <A029A4295D154649BCC3E22A692B2602339DB2@ex10-mbx-9002.ant.amazon.com> (raw)
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
