I was just wondering if there are any GbE controllers out there that do enough of their processing in the driver (or have sufficient control knobs available) that we can experiment with nonstandard collision algorithms, or in any case, as much of frame processing as possible? The Intel controllers I've looked at (8254x) seem to handle most of the actual Ethernet processing in hardware, as you'd expect, leaving the driver to do little more than manage buffers and statistics. We'd like to play around at a lower level. Does anyone have any suggestions? Maybe it's just too much to ask at these speeds?
