  Only 80Mb/s with a 10/100 card  Some time back there was a
discussion on debian-laptop over what the actual throughput of
the so-called "10/100" cards was, on a 100 Mbit network.  The
Xircom website addresses this question:  "Q: What is the
difference between the RealPort CardBus Ethernet 10/100  and the
RealPort Ethernet 10/100?   A: The RBE-100 is a 32-bit
Integrated PC Card which has higher performance, uses less power
and includes power management advantages over the RE-100. The
RBE-100 provides higher throughput with its 32-bit bus-mastering
architecture which increases the data transfer speeds between
the notebook and the network without burdening the PC's
processor. It brings PCI-based performance to your CardBus-
equipped notebook in both 10Mbps and 100Mbps network
environments.  CardBus 32-bit PC Cards (like the RBE-100)
deliver up to 80Mbps networking speeds, while 16-bit PC Cards
(like the RE-100) deliver a maximum of 20Mbps."    (note I'm
