Realtek switches have either 8 or 32 receive queues on the CPU port. This is an overkill. Not only the CPUs have low performance but also the queues need memory (currently ~4MB) and lots of them are rarely used. To mitigate that situation add a new setup routine that enforces CPU packet receiving to a fixed number of queues. From observations one can see that most of the packets (especially TCP) are received on a single queue. To align with the transmit path, start with a limit of 2 receive queues. To make it clear: This commit does not change the receive path or its structures. It simply limits the number of queues that are filled by the hardware.
