IPv6 over Firewire

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.

YOSHIFUJI Hideaki (6):
firewire net: Accept IPv4 and ARP only.
firewire net: Send L2 multicast via GASP.
firewire net: Allocate address handler before registering net_device. firewire net: Ignore spd and max_payload advertised by ARP. firewire net, ipv4 arp: Extend hardware address and remove
driver-level packet inspection.
firewire net, ipv6: IPv6 over Firewire (RFC3146) support.
