[dpdk-users] Failover not working on X520 NIC with ixgbevf driver

[Laurent Dumont]

Can you show the VF settings on the hypervisor? "ip link show
$SRIOV_INTERFACE_NAME"?

We saw similar issue with X710 where the physical state wasn't properly
passed from the actual PF to the VM VF. That meant that failover could not
happen since the VM thought the link was still active. We had to change the
"link-state" parameter on the two VF used by the VM.

That said, it was without VPP but a VM with DPDK enabled.
