[net-next 2/9] i40e: make visible changed vf mac on host

[Jeff Kirsher]

From: Aleksandr Loktionov <aleksandr.loktio...@intel.com>

This patch makes changed VM mac address visible on host via
ip link show command. This problem is fixed by copying last
unicast mac filter to vf->default_lan_addr.addr. Without
this patch if VF MAC was not set from host side and
if you run ip link show $pf, on host side you'd always
see a zero MAC, not the real VF MAC that VF assigned to
itself.
