> Subject: [PATCH] net/i40e: set speed to undefined for default case in link
> update
>
> From: Laurent Hardy <laurent.ha...@6wind.com>
>
> During PF/VF link update, a default speed value of 100M will be set if
> get_link_info has failed or speed is unknown.
>
> Consequently if PF is put in no-carrier state, VFs will switch to "in
> carrier" state
> due to a link up + a link speed set to 100M (default value if no speed
> detected).
>
> To be consistent with linux drivers on which PF and VFs are in same carrier
> state, sets default speed to undefined (instead of 100M) and updates a link
> status of VF only if link is up and speed is different from undefined.
