Subject: [patch net-next v2 00/19] Remove support from bridge bypass for mlxsw/rocker drivers

From: Jiri Pirko <jiri@...lanox.com>

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.
