The ones we used were Digital 21140 genuine tulip based. For a while I
wasn't impressed with the reports I got on the tulip list on the 21143
Intel/tulip based KNE cards, but it seems that several people on the
list are now willing to endorse them so I may give them another try.
I'm going to see if the vendor I'm dealing with can order them as
possible replacements for the 3c905's. I also had somebody write in
that the Netgear FA311 will "work" with the linux drivers posted on the
netgear website, but I'd prefer to run stock kernels in the cluster if I
can so I'm probably going to avoid this option unless/until they get
into a stock kernel. I'm going to have to check out the supported
device list in RH 7.1's 2.4 kernel.
