I've had no end of problems with these adaptors. I spent a few hours looking at the driver & the 21143 specs, and became quite confused.. At one time, I offered to buy Matt Thomas (the driver's author) a 21143 based card. He told me he had some, but no switch.. Maybe we should take up a collection & buy him one ;-) Anyway, the only way I've had any success is by setting the card to 100Mb full-duplex and setting the switch to 100Mb, half-duplex. Somehow, the tulip ends up in half-duplex mode & all is well. If I set both the adaptor and switch to full-duplex (100mb), the card remains in half-duplex and performance is poor.
