Sure, I just don't want to make a mistake on coding it. I'm open.

Since macaddr_manuf() will not be up to date, I'd say lets make
the new function macaddr_brand, and if someone wants to do the other
two, fine.  I'd also doc the fact that macaddr_manuf() is deprecated, marked
for deletion one or two releases down the line (since the table will
no longer be updated, and is very much outdated).

It's on the IEEE site (http://standards.ieee.org/regauth/oui/index.shtml).
