Jiri Pirko 3aeb66176f net: replace br_fdb_external_learn_* calls with switchdev notifier events
This patch benefits from newly introduced switchdev notifier and uses it
to propagate fdb learn events from rocker driver to bridge. That avoids
direct function calls and possible use by other listeners (ovs).
