> Subject: [PATCH v2] net/fm10k: initialize link status in device start
>
> Fm10k host driver can't manage PHY directly and provides a fake link status by
> always reporting LINK_UP. We should initialize link status in device start,
> otherwise application will get LINK_DOWN status when LSC configured.
