> 1) Print incorrect VF MAC or zero MAC
> ip link show dev $pf
> 2) Don't preserve MAC between driver reload rmmod iavf; modprobe iavf
> 3) Update VF MAC when macvlan was set
> ip link add link $vf address $mac $vf.1 type macvlan
> 4) Failed to update mac address when VF was trusted ip link set dev $vf
> address $mac
> 
> This includes all other configurations including above commands.
