All right, I've figured out what I want to do with the packets (though a zero-copy implementation would be faster, I doubt it's easy to do here). I'm going to set up a list of buffers in memory, then feed their address to the chip as needed...(actually, it'll be four rings, since there are 4 DMA channels). What I need to know now is what the best way would be to get the user buffers into the kernel (I'm assuming we'd be trying to send pointers to all four at once, then copying). -- Lee Cremeans -- Manassas, VA, USA (WakkyMouse on DALnet and WTnet) A!
