I am currently working on a 8245 based board with 2.4.27 e100 driver and when taking in (and processing streams), only about 50 Mbps can be handled: about half of the time is based in kernel space (handling interrupts). The eepro100 driver was much worse. As a result, I am a bit wondering about the higher bitrates. How much do you achieve on tests with what hardware? --=20 ash nazg durbatul=FBk, ash nazg gimbatul, ash nazg thrakatul=FBk agh burzum-ishi krimpatul
