The Linux command "ethtool" missing information - IBM BladeCenter HS23 (7875)

Troubleshooting


Problem

The Linux command "ethtool" does not properly support new advertised link modes, Kx4 and KX PHY, used by the affected Ethernet Adapters. When the ethtool ethX command is executed, supported ports, supported link modes, advertised link mode, speed, and port are not reported. This does not effect the functionality of the Adapter.
