Subject: Fix bridge MAC change notification.

This is my first time on netdev. I am writing about the ensuring
that upper network layers are aware of bridge MAC changes due
to re-configuration or port addition/removal.

It seems this topic has cropped up before, with one patch by 
Stephen Hemminger already in 3.0, and a fix for it (sent 7/22)
(http://marc.info/?l=linux-netdev&m=131135705613958&w=2) pending.

The existing patches don't cover the br_del_if case, the case of 
a changing MAC address on a port associated with the bridge, and
the case of manually setting the MAC address, which the following
patch remedies.

Table of Contents:
[PATCH] Bridge: Always send NETDEV_CHANGEADDR up on br MAC change.

Thank you,
A
