The ixgbe driver supports NBASE-T on some devices. However, the advertisement

of NBASE-T speeds is suppressed by default, to accommodate broken network

switches which cannot cope with advertised NBASE-T speeds. Use the ethtool

On Linux systems with INTERFACES(5), this can be specified as a pre-up command
