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. + +Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com> +Reviewed-by: Vladimir Oltean <olteanv@gmail.com> +Signed-off-by: David S.
