I recently tried current and found that my 3c509 card would lockup
within a few seconds of heavy transmittions. I noticed that there is
no timeout code in the current if_ep.c driver and had to put back the
kludge from the 2.1 version, patch below. I'd be interested to know
if you have the card working reliably under current without such a
kludge.
