Hi,
Does anyone know about bus mastering on the 3com 3c59x or 3c900 cards? When I enable bus mastering in the driver, as opposed to PIO, the data rate delivered to the card goes way down. As far as I can see, the kernel is taking about 10ms waiting for the DMA to finish for each transfer. I have heard of other people getting close to 100Mbps on this card, but either due to my kernel, 2.0.23, or my hardware, a Fugu P100, the bus mastering does not seem to work right.
Any help or info is greatly appreciated.
Sincerely, Phillip Dillinger .,
