Nice catch, thanks! The bytecode for inet6($ifgw) looks the same as
what you posted in kern/55403: it jumps to the rest of the rule
matching as soon as one byte of the address matches :/

For the ifaddrs($ifgw) the bytecode uses "unimp 0x27". I'm not sure
what this means, but this seems to behave correctly at least.
