bridge: add local MAC address to forwarding table (v2)
If user has configured a MAC address that is not one of the existing ports of the bridge, then we need to add a special entry in the forwarding table. This forwarding table entry has no outgoing port so it has to be treated a little differently. The special entry is reported by the netlink interface with ifindex of bridge, but ignored by the old interface since there is no usable way to put it in the ABI.
