[PATCH net-next 00/20] bridge: complete netlink support

[Nikolay Aleksandrov]

From: Nikolay Aleksandrov <nikolay@cumulusnetworks.com>

Hi,
This set completes the bridge device's netlink support and makes it
possible to view and configure everything that can be configured via
sysfs. I have tested all of these (setting and getting). There're a few
longer line warnings about the br_get_size() ifla comments but I think we
should have them to know what has been accounted for. I have used the sysfs
interface as a guide of what and how to set. As usual I'll send the
corresponding iproute2 patches later.
The bridge port's netlink interface will be completed after this set gets
applied in some form.

This patch-set is on top of my last vlan cleanups set:
http://www.spinics.net/lists/netdev/msg346005.html

Cheers,
 Nik
