[Gllug] NetGear fa311 NIC only half duplex

[Thomas Robinson]

Use dmesg. Hopefully you will see some usefull information there about
your NIC. If your driver supports mii registers you can use mii-diag
(from Donald Becker http://www.scyld.com/diag/) to get more info on what
your NIC is doing. You'll have to look at the mii word value that is
sent back and compare (do some adding in HEX) with the tables on
http://www.scyld.com/diag/mii-status.html.

Also some drivers (mostly from Donald Becker) allow you to set options
in /etc/modules.conf to force a specific link status.
e.g.
alias eth0 natsemi
options natsemi full_duplex=1 debug=2

# depmod -a
# ifdown eth0
# modprobe -r natsemi
# ifup eth0

Question asked on the irc channel a few days ago but with no real answer
- 
How can you tell whether a NIC is running at full or half duplex?
