Hi All,
I have 4 port card X710 card(i40e driver), on 3 of them i have configured
SRIOV and using one physical port bound to ovs-dpdk. I am observing some
strange behaviour with performance. If i run traffic on VFS and DPDK port ,
performance is better on VFS.
If I remove DPDK port and run traffic, SRIOV VFS starts dropping the
packets.
Card is running in multimode-driver , 3 kernel and 1 OVS-DPDK. I have few
questions
1) what exactly OVS-DPDK(i40epmd) is setting in the global pnics card
registers that is causing better performance of the overall card (VFS as
well as DPDK)
2) To isolate between kernel/dpdk DPDK provides multi-mode driver option,
do we have such option in ovs-dpdk , atleast look up of code/doc didn't
point me to anything.

Thanks and Regards,
