Answer inline and provided other config related information below. Let me
know in case you need any other information.
*eth1 is it the port representor of VF1?*
eth0 and eth1 are port representor for VF1 and VF2 respectively.
*eth0 is the up-link representor?*
ens11 is pf(uplink) interface.
*Can you share dpif/dump-flows so we can see what are the flows you are
trying to offload?*
*[root@localhost ~]# ovs-appctl dpif/dump-flows ovs-sriov*
