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, Pradeep.K.S.
