Re: [PATCH net v3 1/2] net: airoha: handle RX_NO_CPU_DSCP interrupt, not just RX_DONE

airoha_qdma_hw_init() unmasks the per-ring NO_CPU_DSCP interrupt, which
fires when an RX ring runs out of free CPU descriptors, but
airoha_irq_handler() only extracts the RX_DONE bits from the same status
word. The NO_CPU_DSCP bits are acknowledged and dropped.

Once a ring is drained to zero posted descriptors no further RX_DONE can
fire for it - nothing is left for hw to receive into - so NAPI is never
rescheduled, airoha_qdma_fill_rx_queue() is never called again, and the
ring stays dead until the interface is reconfigured.
