[Intel-wired-lan] [next PATCH S7 2/9] i40e: make visible changed vf mac on host

[Alice Michael]

From: Aleksandr Loktionov <aleksandr.loktionov at 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.
