[patch net-next 07/19] mlxsw: spectrum: Remove support for bridge FDB learning sync

[Jiri Pirko <jiri@resnulli.us>]

From: Arkadi Sharshevsky <arkadis@mellanox.com>

Currently the mlxsw driver supports an option for disabling syncing
the hardware learned FDBs with the software bridge. This behavior
breaks the bridge offload model and thus it is removed.
