Tulip Driver

[Allan Lawrie]

Using a Planet EN9501 (v2) card, full-duplex causes constant transmit
errors using the driver with kernel 2.2.12.

When I use Half-Duplex (options=3), it seems to run OK but there are
still errors.

The machine is an AMD K6-200, ASUS P2T4S m/b, should be enough to feed
the card.

I have several of the cards, so if there's nothing obviously wrong, I'll
try some other combinations.
