Controller is "Hewlett-Packard Company NC552SFP 2-port 10Gb Server Adapter"
I got the following from our Linux OS team, stating that they are not able to change the speed to Auto Negotiate or to 1GB ( RHEL support team said that the speed cant be changed – its hard coded) , and are getting the error “Not Permitted” -
Does the below look OK ? Can we change the speed to 1GB ? (as the switch only supports 1GB link)
ethtool eth4 Settings for eth4: Supported ports: [ FIBRE ] Supported link modes: 10000baseT/Full Supports auto-negotiation: "No Advertised link modes: Not reported Advertised pause frame use: No Advertised auto-negotiation: No Speed: Unknown!
