Nope, not seeing that here:

steve at mjolnir:~$ sudo ifconfig eth2 up
steve at mjolnir:~$ cat /proc/interrupts | grep eth2
 70:          0          0          0          0     GICv2 294 Level     eth2

I'm currently using mainline HEAD from a couple of days back, so
4.16-rc3+ : 5d60e057d127538113d8945ea87d916fccee93fe
