-Enable only those interrupts that we can handle & acknowledge in the
-interrupt handler.
-
-At least on EdgeRouter Lite, the hardware may occasionally interrupt with
-some error condition when the physical link status changes frequently.
-Since the interrupt condition is not acked properly, this leads to the
-following warning and the IRQ gets disabled completely:
-
-[ 41.324700] eth0: Link down
-[ 44.324721] eth0: 1000 Mbps Full duplex, port 0, queue 0
-[ 44.885590] irq 117: nobody cared (try booting with the "irqpoll" option)
