Trying to set the speed or advertise the correct speed also not working.
ethtool -s eno7 speed 10000
Cannot set new settings: Invalid argument
not setting speed
ethtool -s eno7 advertise 0x1000
Cannot set new settings: Invalid argument
Is there any more thing i can try, does using other cable such as cable from Intel a possible solution?
