    The relationship about QueuePair & TX Queues & TC(Adapter Queues)



      Recently, I have been learning the RDMA adapter hardware behavior.

      When RDMA applications issue network I/O, they post Work Requests to QueuePair and ring doorbell of the adapter.

      Then adapter will process their requests in TC(traffic class, hardware queues on the adapter).

      But when I check the adapter, I find some puzzling things:

      p4p1 is my CX5-EN adapter. There are 24 RX queues and 192 TX queues.

      What are these queues used for?

      Thank you.
