That's a *very* high load percentage. We put over 20MB/sec through old P100
systems with two fast ethernets channel bonded using Tulip 21140 cards on
2.0.30, and it put about that load (slightly less) on the system.

The bandwidth number depends on the duplex. A few chips, such as the 8390
used on the NE2000, cannot do back-to-back transmits and will be somewhat
lower than the peak.
