It doesn't, it still performs poorly with any of the three available
drivers -- xircom_cb, xircom_tulip_cb, and tulip_cb (from the pcmcia package):
* Rx gets only about 1.8Mbit/s on a 100Base-TX network with any of the three
* Tx gets 80+Mb/s with xircom_tulip_cb and tulip_cb, and less than 30Mb/s
with xircom_cb.
And no, promisc mode played no role in this experiment, because my test
network is switched and otherwise very quiet.
Windows drivers handle both Rx and Tx at full speed.
I have this feeling that we're handling the card in some (tulip) compat
mode, which severely cripples performance. It's hard to tell, without
docs...
