You would think that someone using Linux in a production setting for the
last 9 years could figure this out..... But what is Redhat 's recommended
way of setting a nic cards speed / duplex at boot time?
In my specific case I have a Dell poweredge 2550 using the tg3 nic card
driver. ethtool seems to be able to query this device fine, but when
attempting to change a setting with "ethtool eth0 -s autoneg off speed 100
duplex full " nothing seems to happen. I do seem to be able to make
changes with mii-tool but ethtool does not report that changes have
occured...
I noticed that /etc/sysconfig/network-scripts/ifup has a $ETHTOOL_OPTS
definition that it checks for... but none of the documentation mentions
where to define this... nor does there appear to be a mii-tool equivilent
definition. You would think something this basic would be
simple to do/figure out and perhaps even documented somewhere :)
