> This callback doesn't seem to serve much purpose, and prevents things
> like:
> 
>     - systemd.link files from disabling autonegotiation
>     - carrier detection in NetworkManager
>     - any ethtool setting
> 
> prior to userspace bringing the link up.
> 
> The only fear I can think of is accessing unclocked resources due to
> pm_runtime, but ethtool ioctls handle that as of commit
> f32a21376573 ("ethtool: runtime-resume netdev parent before ethtool ioctl ops")
