Extend MAC support to support also lag interfaces:
1. In case an entry is learned on a port that is part of lag interface,
then notify the upper layers that the entry is learned on the bond
interface
2. If a port leaves the bond and the port is the first port in the lag
group, then it is required to update all MAC entries to change the
destination port.
