Subject:   Making clists bigger...

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.
