Hi,

UDP checksum cannot be computed by Hardware virtualization( Intel 82599
SRIOV PCI passthrough, DPDK V1.7 ).UDP bad checksum errors are observed in
the tcpdump(pcap) collected after host on the Service router when the UDP
checksum computation is Hardware offloaded.

Thanks,

UDP checksum is set  to 0  and Hardware offloading is disabled to prevent
the UDP checksum errors.

Is this the only way out?Is there  Hardware virtualization limitation with
respect to UDP checksum computation?Please suggest how to resolve UDP bad
checksum errors with Hardware offloading set ?
