Receive queue setup involves allocating memory for the queue,
initializing data structure representing the queue and filling queue
with receive buffers of rx descriptor count. Receive queues are referred
as droq. Hardware fills the receive buffers in queue with the packet.
In receive queue release, receive buffers are freed along with the
receive queue.
