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

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
