Merge branch 'mlxsw-bridge-vlan-offloading'

Browse Source 
Ido Schimmel says:

====================
This patchset introduces support for the offloading of 802.1D bridges
between VLAN devices. These can either be VLAN devices configured on top
of the physical ports or on top of LAG devices.

Patches 1-2 deal with the necessary infrastructure changes needed in order
to enable the above. The main change is that switchdev drivers can now know
the device from which the switchdev op originated from.

Patches 3-10 lay the groundwork for 802.1D bridges support in the mlxsw
driver, with patch 4 doing most of the heavy lifting.

Patch 11 finally offloads these bridges to hardware by listening to the
notifications sent when the VLAN device joins or leaves a bridge. It is
very similar to the already existing 802.1Q bridge we support.

Patches 12-14 add minor modifications to allow one to bridge a VLAN device
configured on top of LAG.
