Hi,
Setup :
Namespace (no DPDK) <--> veth1 --- veth0 type dpdk-af-packet <--> ovs-dpdk.
TCP packets generated at the namespace have wrong TCP checksum (probably not calculated ). ICMP/UDP is OK.
If I disable the tx-hw-offload - TCP is running but performance is degraded (probably huge degradation)
In native OVS (i.e. no DPDK) - there is no problem.
Is this a bug ?
Best Regards
avi
