I don't know what uses the mii code but my drivers dont :)

As for the Intel published version, its my same code but there tends
to be some varations due to the time involved in the machinery
within Intel to release something.

A couple years ago there was a pretty big gap between the
FreeBSD CVS code and the Intel, but since I took this job
I have been working hard to bring the two as close together
as possible.

For instance, right now the latest driver for 6.3 or 7.0 is
newer than that 6.6.6 driver.

In any case, I am the owner of both streams so you know
who to call if you have problems :)

BTW, I'm on vacation (home reading, relaxing, and playing
a lot of bass) so other than email don't expect anything from
me til 1/7 :)
