The thing is, I don’t see empty TCP packet drops on DPDK computes, I
nevertheless applied the patch HAN mentioned on DPDK computes, no difference.
The issues we see is on OVS computes.

Does OVS 2.11.0 support TSO in OVS-DPDK? Or are there any separate
configurations to be done or patches to be applied?

Basically, I want to run a VM2VM (same host) iperf test and thus want to
enable TSO for the vhostuser backend. But, I am not able to figure out how
can I turn ON this feature in guest VMs. ethtool is unable to change these
fixed features. Either some change in domain XML or some change in OVS-DPDK

1. This issue is with native OVS firewall where the data flows are subject
to conntrack rules, there is no issue for hybrid firewall
1. Below is from DPDK compute:

The node you are displaying below is running kernel datapath
fyi: The fix Han pointed you to is for userspace datapath/conntrack

1. The hybrid firewall refers to Linux bridge based firewall. To debug the
issue, we switch the neutron OVS agent to use native firewall.

Sorry, I overlooked your questions on dpdk computes. DPDK itself is find, VMs
are up and running.
