We have used the Intel Pro / 1000T. Intel has linux drivers for both
the 2.2 and 2.4 kernels. Using 3 streams of ftp to between 2 gigabit
ports, I have gotten a 59MBS aggregrate but cpu busy goes to 93% on
a dual 800MHz system. The 2.4 kernel can do about 50% better on the
same test. The two hosts were connected by HP4000 switch.
