 Description   

Concurrent sends tunable was intended to limit the number of in-flight transfers per connection. However queue depth does the exact same job. So for example if the queue depth is negotiated to 16 and concurrent_sends is set to 32, the maximum number of in-flight transfers doesn't exceed 16. There is no need to keep concurrent_sends around since it doesn't add any unique functionality.
