This can be used by an application to split the incoming flows among worker
threads based on the RX queue on which the packets associated with the flows
are received. It allows each worker thread to be associated with a NIC HW
receive queue and service all the connection requests received on that RX
queue. This mapping between a app thread and a HW NIC queue streamlines the
threads based on the RX queue on which the packets associated with the
flows are received.
