Hello,
I am trying to run VPP in a VM with four SR-IOV virtual function
interfaces, two on a ixgbe/ixgbevf and two on i40e/iavf.
The ixgbe interfaces seem to work fine, but the i40e interfaces fail to start:
vpp# show inter
Name Idx State MTU (L3/IP4/IP6/MPLS)
Counter Count
VirtualFunctionEthernet1/0/0 1 down 9000/0/0/0
VirtualFunctionEthernet2/0/0 2 down 9000/0/0/0
VirtualFunctionEthernet3/0/0 3 error 9000/0/0/0
VirtualFunctionEthernet4/0/0 4 error 9000/0/0/0
local0 0 down 0/0/0/0

Thankful for any hints on how to keep troubleshooting this.
