> Add support for port reset in rte layer.This reset
> feature can be used not only in vf port reset in the following
> code develop process later, but also pf port.But in this patch
> set, we only limit the discussion scope to vf reset.
> This patch add an API to restart the device.
> It's for VF device in this scenario, kernel PF + DPDK VF.
> When the PF port state is down->up, APP should call this API to
> restart VF port. Most likely, APP should call it in its
> management thread and guarantee the thread safe. It means
> APP should stop the rx/tx and the device, then restart
> the device, then recover the device and rx/tx.This API can
> also do some restore work for the port.
