Merge branch 'systemport-net'
Florian Fainelli says:
====================
net: systemport: RX path and suspend fixes
These two patches fix a race condition where we have our RX interrupts
enabled, but not NAPI for the RX path, and the second patch fixes an
issue for packets stuck in RX fifo during a suspend/resume cycle.
====================
