Donald Becker has left NASA and formed his own company. A better site is: http://www.scyld.com/ And, for gigabit ethernet info, see: http://www.scyld.com/expert/100mbps.html#1000baseF (BTW, I spoke with Donald last summer at USENIX. I was concerned that, having left NASA to form his own business, he might no longer have time to write Linux ethernet drivers. He reassured me that the work would go on. The consulting that he was going to (or at least hoping to) do would be for very well-heeled customers like government labs building Beowulf clusters. Also, the driver situation has changed considerably since the days when he'd have to beg a vendor for documentation so that he could write a driver; because of Linux's visibility these days, documentation and even boards are easy to come by. Also, many vendors are now writing their own drivers, though, unfortunately, they aren't always open source.)
