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 :-)
