net: bridge: multicast: notify switchdev driver whenever MC processin…
…g gets disabled commit c832962 upstream. Whenever bridge driver hits the max capacity of MDBs, it disables the MC processing (by setting corresponding bridge option), but never notifies switchdev about such change (the notifiers are called only upon explicit setting of this option, through the registered netlink interface). This could lead to situation when Software MDB processing gets disabled, but this event never gets offloaded to the underlying Hardware. Fix this by adding a notify message in such case.
