   Anyway, this is e100 version 2.0.19, with lots of changes by the Intel
   folks at my request.

Ben, I'm going to put your report in the same classification
as "root cat'd crap into /dev/kmem and the kernel crashed".

If you are programming the PHY directly with MII IOCTLs you are on
your own.  I personally refuse to monitor how the user pokes at the
MII in my drivers to try and cope with the user putting the PHY into a
weird state that the driver would otherwise never need to deal with.

It is not a bug, pure and simple.
