In the next patch, responsibility for sending notification is moved from
the core to the driver that implement fdb_add (and fdb_del in the patch
after that). In this patch, export a helper that the core currently uses
for sending FDB notifications for the drivers to use as a fallback if there
is nothing specific to report.
