> Currently a user is not allowed to clear a VF's administratively set MAC on the
> PF. Fix this by allowing an all zero MAC address via "ip link set ${pf_eth} vf
> ${vf_id} mac 00:00:00:00:00:00".
> 
> An example use case for this would be issuing a "virsh shutdown"
> command on a VM. The call to iproute mentioned above is part of this flow.
> Without this change the driver incorrectly rejects clearing the VF's
> administratively set MAC and prints unhelpful log messages.
> 
> Also, improve the comments surrounding this change.
