Merge branch 'bcmgenet_systemport' 

Florian Fainelli says:

====================
net: bcmgenet & systemport fixes

This patch series fixes an off-by-one error introduced during a previous
change, and the two other fixes fix a wake depth imbalance situation for
the Wake-on-LAN interrupt line.
====================
