> The default adapter configuration callback is invoked when a Rx
> queue is added to the adapter and the adapter detects that a SW
> service is needed. The adapter needs to re-configure the device
> with an additional port and to do do, it needs to stop the
> device and restart it after it is done reconfiguring it. This
> patch adds code to check the return code of
> rte_event_dev_start() for both when the reconfiguration fails
> and when it succeeds and introduces a new error code (-EIO)
> for the first case.
