The selection flags for the RX hash define how the received packets will
be distributed between multiple queues.
When creating a new TIR, the queue_num is set to 1 if non of the selection
flags is set.
Applied the same to the RSS desc before checking if it matches a cached
TIR object to save creating a new object every time.
