> The drivers should update the state to be stopped when the queue stop
> callback is done successfully or when the port is stopped.
> The drivers should update the state to be started when the queue start
> callback is done successfully or when the port is started.

> The driver wrongly didn't update the state to be started when the port

> Following call to a queue stop API was not completed by ethdev layer
> because the state is already stopped.

> Move the state update from the Tx queue setup to the port start
