Why not do it like this:
- LA set ==> use a keyword like "local" - LA clear, MC clear ==> resolv(manuf) - LA clear, MC set ==> strip MC and resolv(manuf) ie 04:05:06 -> Xerox 05:05:06 -> Xerox 06:05:06 -> Local 07:05:06 -> Local I can't imagine myself situations where you locally assign an address and still be interested in the manufacturor of the card from which the mac was used as seed. I usually use a BCD encoded vlan-tag-number as the LA-mac, this would result in something like "Local_00:01:30" for vlan 130 :-) Cheers, Sake _______________________________________________ Wireshark-dev mailing list [email protected] http://www.wireshark.org/mailman/listinfo/wireshark-dev
