Can you tell me, with the ethtool -i output, if I'm running the appropriate firmware? # ethtool -i enp129s0np1 driver: nfp version: 4.18.0-2.el8.x86_64 SMP mod_unl firmware-version: 0.0.3.5 0.21 nic-2.0.7 nic expansion-rom-version: bus-info: 0000:81:00.0 supports-statistics: yes supports-test: no supports-eeprom-access: no supports-register-dump: yes supports-priv-flags: no If this is a firmware version case, then we should really improve the errors we are giving the user, the -EINVAL can be anything.
