> Subject: [PATCH net,v2] hv_netvsc: Register VF in netvsc_probe if
> NET_DEVICE_REGISTER missed
>
> If hv_netvsc driver is unloaded and reloaded, the NET_DEVICE_REGISTER
> handler cannot perform VF register successfully as the register call
> is received before netvsc_probe is finished. This is because we
> register register_netdevice_notifier() very early( even before
> vmbus_driver_register()).
> To fix this, we try to register each such matching VF( if it is visible
> as a netdevice) at the end of netvsc_probe.
