Subject: macb napi strange behavior

Hello,

I'm trying to determine why I have a huge number of IRQs for only a
macb interface and the other one works just fine (low IRQ activity). I
have activated IP forward and I'm just forwarding packets from eth0 to
eth1.
The platform is Zynq7, Linux kernel 4.0, vanilla macb.

cat /proc/interrupts:
[...]
144:     679425     0       GIC  54  eth0
145:   17867097          0       GIC  77  eth1
[...]

Any ideas?

Best regards,
Nicolae Rosia
