Regardless of the number of receive queues (8 or 32) the interrupt status and mask registers are built up bitwise in the same way: - 8/32 rx run out interrupts - 8/32 rx done interrupts - 2 tx tone interrupts - 2 tx all done interrupts - 3 L2 notify interrupts (only RTL839x) So one can always derive the bit position of those fields by using the device specific rx_rings configuration setting. To simplify the code these registers will be handled by central helpers in the future. In a first step provide a interrupt base register definition that points to the first interrupt type - aka the rx run out interrupts. To not overcomplicate things simply reuse the existing DMA_IF_INTR_MSK and DMA_IF_INTR_STS naming convention. Until all gets fixed the runout registers on RTL93xx will be accessible by that name.
