    These lock the fast forwarding hash table with a lock per hash bucket.
    There is one known issue with these changes: a LOR with the bridge code
    caused by holding a lock across the call to forward the packet. Also, some
    statistics are not consistently updated.

    Beware of overlap with routing table locking changes.
