Hi !
Thanks in advance.
I have a 2 Dell servers with Intel® Ethernet Server Adapter I350-T4 NICs
Do you have a build of ethtool that can access EEE ?
# ./ethtool --show-eee eth3
Cannot get EEE settings: Operation not supported
I am running DRBD with crossover cables and the NICs switch themselves off when
there is no traffic.
I have passed the module parameter to disable EEE (EEE=0) but the NICs are
still doing the same.
If I could get ethtool to control EEE then I could configure Xenserver to pass
the ethtool command.
I have recently compiled ethtool & igb driver.
# ./ethtool --version
ethtool version 3.7
