Identifying and Removing Previously Installed Drivers - UG1586

You can identify any previously installed sfc drivers using the ethtool -i command:

• An ‘in-tree’ driver uses one of the following formats for its version number:
  • On older versions of Linux, the ‘in-tree’ driver outputs only Major and Minor revision numbers:

    # ethtool -i enp3s0f0
    driver: sfc
    version: 4.0

  • On recent versions of Linux, the ‘in-tree’ driver instead outputs the kernel version number:

    # ethtool -i enp3s0f0
    driver: sfc
    version: 4.18.0-372.9.1.el8.x86_64

• All other sfc drivers display detailed version information:

  # ethtool -i enp3s0f0
  driver: sfc
  version: 4.15.12.1008

To remove the previously installed driver (with Onload uninstalled or not yet installed):

# find /lib/modules/$(uname -r) -name 'sfc*.ko' | xargs rm –rf
# rmmod sfc
# update-initramfs -u -k <kernel version>

initramfs commands might differ on different Linux based OS, for example on CentOS 7 the following dracut command can be used:

# dracut –f
