Hello,
Currently, I manage gentoo system that have a variety of 10 and 100 MB/s
ethernet cards. I use lshw to distinguish the max ethernet port speed:
For example:
network:0 DISABLED

duplex=full ip=192.168.2.17 latency=32 link=yes maxlatency=10 mingnt=10
module=3c59x multicast=yes port=MII speed=100MB/s
Is this reliable? What if a 10/100 card is plugged into a 10MB/s hub?
Is there other software to discern the hardware capability and test
actual throughput?
How comfortable are you with the results you get? (reliable?)
curiously,
James

Have you tried mii-tool?
quasar ~ # mii-tool -v int0
int0: negotiated 1000baseT-FD flow-control, link ok
product info: Yukon 88E1011 rev 5

Some NICs work with mii-tool, others with ethtool. The latter is
generally the more modern one.
