Currently, I am using this one with the xe driver, but performance is rather bad (about 1.2 MBytes/sec). According to if_xe.c, this is due to the way the card is handled by the driver: * Note that the crappy PIO used to get packets on and off the card means that * you will spend a lot of time in this routine -- I can get my P150 to spend * 90% of its time servicing interrupts if I really hammer the network. Could * fix this, but then you'd start dropping/losing packets. The moral of this * story? If you want good network performance _and_ some cycles left over to * get your work done, don't buy a Xircom card. Or convince them to tell me * how to do memory-mapped I/O :) So what do people recommend here?
