MAC address in DHCPv6 DUID

[Dave Taht]

Hmm. As noted one of the interfaces in this particular product uses a
flipped 'local' bit, as the manufacturer doesn't supply 1 of the 4 needed
mac addresses.

However, the vifs (the wireless interfaces) are generated at run time. It
would be bad to use those by default.
