https://community.intel.com/t5/Software-Archive/UDP-bad-checksum-error-for-packets-sent-by-my-DPDK-application/m-p/1176949#M79528 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?
