The patch adds mdio_read() at the end of open() -- this shouldn't have any
effect -- and doesn't on my system.
But it's inexpensive and I'll it to my next driver release.

This fixes a race condition triggered by rapid additions or deletions to the
multicast filter list.
I'm coming up with a better fix that adaptively puts the chip in
Rx-all-multicast mode when manipulating the list, and only goes through the
slow process of installing the multicast filter when the list is stable.
Installing the multicast list turns off both the transmitter and receiver!
It's slow with long lists because the chip computes the hash filter table
from the multicast addresses themselves, rather than taking a precomputed
table as most other chips do.

v1.03 is stable in normal operation. The two operations that will kill it
are:
rapidly changing the multicast list (complex fix: just get v1.04).
running out of memory (fix: move the rx_work_limit check to the top of the
loop)

This problem is chip version specific.
