Do we need to configure Interrupt rate limiting on the processor per application basis? If so, can I configure it on only selective interrupts?
Can an RTOS guarantee that interrupt latency will never exceed a predefined maximum?

If the amount of traffic is low, the device won't delay the interrupts (low latency/bandwidth). Only if the interrupt rate is going up, and there is still FIFO space available, the interrupt rate will be limited, which trades off higher latency for higher bandwidth. Consult the documentation of any devices capable of interrupt rate limiting for exact details of this option.
