Merge branch 'ipv6-firewire'
YOSHIFUJI Hideaki says:
====================
This is take 4 of supporting IPv6 over Firewire (IEEE 1394) based on
RFC3146.
Take 3->4:
- Fix receiving 1394 ARP, which comes without arp$tha.
- Remove rfc3146 unit directory on module exit.
- other minor clean-ups - minimize diffs.
====================

To compile this driver as a module, say M here: The module will be
called firewire-net.
