7.Use the ethtool command to check the parameter configurations that apply to the nxge driver.

(For 10G)

#ethtool -i eth4 driver: nxge version: 2.0.1

firmware-version: 2XGF PXE1.47 FCode 3.9 07/04/24

bus-info: 0000:84:00.0

(Equivalent for 1G)

#ethtool -i eth4 driver: nxge version: 2.0.1

firmware-version: QGC PXE1.47 FCode 3.9 07/04/24

bus-info: 0000:02:00.2

▼To Remove the Driver From a Linux Platform
