Work around a bug I've seen on Linksys EC2T cards. For some reason,
as yet unknown, those cards report their MAC address a byte at a time.
However, other AX88x90 cards report the MAC address a word at a time.
Add a heuristic which looks at the high order bytes of the first 6
words. If they are all '0', assume the card is behaving like the
Linksys EC2T card. Since the default prefix for these cards appears
to be 00:e0:98, this appears to be a safe heuristic. While some cards
have been observed with different prefixes, they all work with this
I'm unsure if this is a bug in the EC2T card, or if it is a bug in the
initialization of the card. No other OS has this heuristic (although
w/o it, the MAC address that is used works).
