command line options for linux nc31xx ,nc61xx ,nc67xx drivers

[Frank Breitgoff]

Hi experts,
are there any driver options available for the mentioned drivers regarding speed und duplex mode? We want to start the nics in 100mb or 1000mb full duplex mode while booting , NO AUTOSENSE! Wanted for any linux driver version, esp. for Red Hat 7.x
I downloaded some drivers but didn`t find any documentation of command line options.
Any help is highly appreciated, thanks.

1000 base T cards in general can't tolerate any setting except autonegotiate.

They tend not to come up in any other mode. They start up, figure out what speed the hub or switch and gets going.

With this going for them, the driver writers may have been smart enough to not provide command line options for the card. The Linux kernel is pretty good at getting that right anyway.

thanks for your reply,

you're right. It wasnt very bright to ask for the Mbit NICS
but with the 100 Mbit (nc31xx) we have an actual problem because our core switch ports are preset for 100 mbit full duplex, autosensing off. the nics must work with these settings immediately after booting, for several reasons

are there any suitable options for these cards?
thanks again for help

What driver do they use?

The 'modinfo ' should give you the options it takes (in /etc/modules.conf) in order to set those things.

If you can't figure it out, just post back which driver it uses, and we'll see what we can figure out.

check out ethtool (included w/RH AS 2.1).

We use it to lock down 100 fd on 1000bt interfaces when we hook them up to 100btx ports.

from rc.local:

ethtool -s eth0 speed 100 duplex full autoneg off
ethtool -s eth1 speed 100 duplex full autoneg off
