NAPI is also known as RX Polling. From what I understood it's a way of 
buffering ingress packets at layer 2 and not generating an IRQ for every 
packet it receives. It's available for Intel Pro/1000 (epro 1000).

I use broadcom pci-x cards (bge) BCM5702X.

For what I see there is a problem with IRQ limit in NetBSD. On other 
machine I have a pgsql that sometimes goes also at around 30k IRQs/sec 
and also suddenly reboots (don't ask me what that pgsql is doing there, 
some strange half-page select that is driving that multi-proc machine 
into nuts - 30k tlb shootdowns IRQs).
