The comments about broken boards due with the hardware not wiring up byte
enables. The problem in that case is a board limitation, not a 91c1111.
After you pointed out the mac needs to be unsigned, I went though and
changed "all" mac references. Seems like there were a couple more than your
patch had. The kernel drivers I have for this already have your fix, and
treat mac's correctly through out.
