Merge branch 'bridge-sysfs-rtnl-notifications'

====================
bridge: support sending rntl info when we set attributes through sysfs/ioctl

This patchset is used to support sending rntl info to user in some places,
and ensure that whenever those attributes change internally or from sysfs,
that a netlink notification is sent out to listeners.

It also make some adjustment in bridge sysfs so that we can implement this
easily.

I've done some tests on this patchset, like:
[br_sysfs]
  1. change all the attribute values of br or brif:
  $ echo $value > /sys/class/net/br0/bridge/{*}
  $ echo $value > /sys/class/net/br0/brif/eth1/{*}

  2. meanwhile, on another terminal to observe the msg:
  $ bridge monitor

[br_ioctl]
  1. in bridge-utils package, do some changes in br_set, let brctl command
  use ioctl to set attribute:
         if ((ret = set_sysfs(path, value)) < 0) { -->
         if (1) {

  $ brctl set*

  2. meanwhile, on another terminal to observe the msg:
  $ bridge monitor

This test covers all the attributes that brctl and sysfs support to set.
