This is a patch to get the DC to get an IP address via DHCP across a bridge.

We weren't getting an IP address when the Dreamcast wasn't directly connected to the router
This seemed to be related to how dcload handles packets.
The offer comes across as a non-ARP broadcast packet. So the Dreamcast was just dropping the packet.
This patch checks for the type of packet and shunts it to the other packet processing function.

TODO:
This all feels kind of dirty.
I think I saw some circular bits in it as well.
I might take a swing at straightening some of this out.
