IPv6 over Firewire

• One day, someone asked a question about allocating memory for Neighbor Discovery message for IPv6, to implement IPv6 over Firewire.

• I was curious why he needs such a thing...

• I looked into driver/firewire/net.c (which implements IPv4 over Firewire (RFC2734) and found that it parsed/modified packets.

• BAD, BAD, BAD!!!

• IPv6 NDP is more flexible (or say, complex) than IPv4 ARP.
• NDP has strict state machine; it is more difficult to maintain it in the driver layer.
• Drivers should be simple as possible
• IPsec (or SEND) will not work.
• I could not not believe that IPv6 over “media” specification requires such nasty design...
