Merge branch 'net-Remove-support-from-bridge-bypass-for-mlxsw-rocker-drivers' 

Jiri Pirko says:

===================
net: Remove support from bridge bypass for mlxsw/rocker drivers

Currently setting bridge port attributes and adding FDBs are done via
setting the SELF flag which implies unconsistent offloading model. This
patch-set fixes this behavior by making the bridge and drivers which are
using it to be totally in sync.

This implies several changes:
- Offloading bridge flags from the bridge code.
- Sending notification about FDB add/del to the software bridge in a
  similiar way it is done for the hardware externally learned FDBs.

By making the offloading model more consistent a cleanup is done in
the drivers supporting it. This is done in order to remove un-needed
logic related to dump operation which is redundant.

First add missing functionality to bridge, then clean up the mlxsw/rocker
drivers.

v1->v2
- Move bridge-switchdev related stuff to br_switchdev.c as suggested by Nik
