firewire: add IPv4 support
Implement IPv4 over IEEE 1394 as per RFC 2734 for the newer firewire
stack. This feature has only been present in the older ieee1394 stack
via the eth1394 driver.
Still to do:
- fix ipv4_priv and ipv4_node lifetime logic
- fix determination of speeds and max payloads
- fix bus reset handling
- fix unaligned memory accesses
- fix coding style
- further testing/ improvement of fragment reassembly
- perhaps multicast support
