It should be easy to deal with this, actually.

The only interrupt-driven MII accesses that happen is the mii_tick()
stuff that is controlled completely by the driver.  This is so e.g. you
could call mii_tick() from an MII-change interrupt, if your hardware
has that -- or you could use the periodic-task-in-thread-context stuff
that the USB code has to do the one-second MII tick operation.  Then all
the stuff would happen from thread context, and there would be no trouble.
