Tulip or De4X5 driver?

[gshamov <gshamov ksu ru>]

Hello!

We have a cluster built from eight DS10L machines (under RedHat 6.2
Linux-Alpha),linked with Fast 100mb Ethernet  switcher.

1) Is it possible to aquire full-duplex, 100MB network performance for
   our hardware configuration?

2) Which network card driver gives better performance -- Generic
   DE4X5 or Tulip? And how to configure these drivers for maximum
   network speed? We have experimented with both of them, using
   kernels 2.2.18 and 2.4.2 -- it seems that its impossible to have
   Full-Duplex with DE4X5... But it seems that network with FDX Tulip
   is slower than in case of Half-Duplex De4X5... What shoulde we do
   wit it?!!

May be someone there had such a experience with these DS10L systems?
Any suggestions will be gratefully appericated!
