caveat, dc supports a lot of chips, some are good, some are junk.
definately excellent are the original DEC (now intel) 21143s. Still the
best 100 MBit/s chips ever built I'd say.
however, if you're buying new NICs now, I'd suggest getting GBit
ones... most of them have the ability to offload more shitz to the
card, especially the checksumming, which I have seen to make a
difference of over 10% in CPU usage with real world applications.
Some even implement checksum offloading correctly - you wouldn't guess
how many fuck that up... the intel gigabit cards are a safe bet usually.

Unix is very simple, but it takes a genius to understand the simplicity.
