Subject: [patch 5/5] d80211: allow wireless vlan interface to have same MAC an AP interface

From: David Kimdon <[email-masked]>

Wireless vlan interfaces need to have the same mac address as
AP interfaces.  The STA must not see the change when it is bound to
a specific vlan, so the address of the vlan interface must be the same
as the address of the AP interface the station associated with.
