Comment 60 for bug 279102

@JC: I didn't fix the bug, just debugged it with that code to check WHY its resetting

David Miller (the driver dev) answered me on the mailing list with:

The problem is that we need to know if a receive FIFO overflow
puts the chip into a state where it must be reset.

And until we know that, we cannot simply exclude that condition
from the reset test.
