Its probably reasonable to start with support for some well known
packets (there are several), including AMD Magic Packet (TM) and ARP. A
bit mask of "capabilities" might be helpful here, too.
I doubt many sites, if any, are using the other more advanced (and
generally not uniformly implemented) features -- such as bitmasks,
security fields (there is even a challenge/response scheme supported by
one vendor!), etc.
