I was not aware of this one. Thank you for pointing this out.
If I correctly understand, devlink_compat_running_version() is
supposed to allow ethtool to retrieve the firmware version from
devlink, right?

Currently it does not work. I guess it is because I am not using
SET_NETDEV_DEVLINK_PORT()? I initially thought that this was optional.
I will continue to investigate and see if it is possible to completely
remove the .get_drvinfo() callback.


Yours sincerely,
