Hi All,
Trying to test E810 Sr-IOV based nic card with 20.11.3 dpdk. I am running
the host kernel driver and only the VF is attached to the VM where I am running
dpdk. But when I attaching the VF to the testpmd it is throwing the below
error. Is there are way to move forward here ?
[root@connexip linuxadmin]# ./dpdk-testpmd -c 0xf -n 4 -a 08:00.0 -- -i

I do see the matching list for driver but is this required even if I use kernel
driver on the host and only IAVF PMD on the guest ?
