To show the limitation of ethtool 4.5 when used to config xl710.
ethtool 4.5 & xl710
XL710 NMC users
In some old linux OS, the ethtool maybe also very old. For example, if it is older than version-4.5, and if there is a XL710 NIC in your system.
When you use ethtool to read out link status, the “Supported link modes” will show as “Not reported”.
If you have this problem, please update ethtool to a version newer than version-4.8.
You can get ethtool from the following link.
The following is the steps to install it.
# tar zxvf ethtool-4.8.tar.gz
# cd ethtool-4.8/
# make install
