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?
