I was wondering how one goes about adjusting the size of driver clists, or whether this is done automatically. I'm working on a serial card with a 2KB transmit buffer, and a 4-8KB receive buffer. I remember reading that clists throttle themselves around 1KB. I'd like to be able to generate clists that are roughly between 1 and 4 times the hardware buffer sizes, so that we can reduce the number of I/O operations to the board (ie - be able to do one 2KB transfer, rather than 2 1KB transfers). Thanks for your help. -Brian
