Subject: [dpdk-users] UDP bad checksum errors for packets sent by DPDK application
Date: Wed, 29 Aug 2018 08:28:38 +0530 [thread overview]
Message-ID: <CA+17DaVx2BwM+RdhmOtqB4zogg4YmbznSojVJAsFWeKCrFqGEw@mail.gmail.com> (raw)
Hi,
I am working with Intel 82599 VF.We have used DPDK v1.7 and RHEL 6.2.On the
host end we have ixgbe driver and on the guest igb_uio driver.Iam seeing
"UDP: bad checksum" messages for the packets sent by my DPDK application to
a socket on a remote machine.A capture external to my VMs show that in the
failing case Tx UDP checksum is incorrect.
ethtool output on the port shows tx-checksumming on.Can the UDP checksum
error be related to Hardware checksum offloading.
Any thoughts? What else needs to be checked?
Best Regards,
Anupama
