> 
> During reset recovery iavf_dev_start() might fail (typically -EIO

> active, leaving the VF down and requiring manual intervention
> to recover.

> Added a start_pending flag: when device start fails during recovery,
> defer it instead of erroring out and resume it from newly added
> iavf_resume_pending_start() on the next link-up event, so the
> VF comes back automatically.
