Felix Fietkau c44506fcbd cns3xxx: fix an rx irq handling corner case ... When an rx interrupt comes in, rx interrupts are disabled and NAPI polling is scheduled. During the NAPI poll, the driver first processes received frames in the ring, then fills the dma descriptor slots with new buffers and calls tx complete, before finally re-enabling rx interrupts and completing NAPI (if below the budget). If the hardware rx queue overflows before the napi complete is called, the hardware will not throw any further rx interrupts and rx processing stops completely. Fix this by keeping NAPI polling scheduled until it completes a poll without receiving any packets, and also handle NAPI completion before refilling rx or completing tx.
