> Subject: [PATCH v3 2/7] net/iavf: defer device start when PF VSI not ready
> 
> During reset recovery iavf_dev_start() might fail (typically -EIO
> from VIRTCHNL_OP_CONFIG_VSI_QUEUES) because the PF VSI is not yet
> 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.
> 
> Fixes: 3e6a5d2d310a ("net/iavf: add devargs to enable VF auto-reset")
