-Subject: net: dsa: qca8k: add support for mdb_add/del
-
-Add support for mdb add/del function. The ARL table is used to insert
-the rule. The rule will be searched, deleted and reinserted with the
-port mask updated. The function will check if the rule has to be updated
-or insert directly with no deletion of the old rule.
-If every port is removed from the port mask, the rule is removed.
-The rule is set STATIC in the ARL table (aka it doesn't age) to not be
-flushed by fast age function.
