For some reason on Armada 3720 boards (EspressoBin and Turris Mox) the
networking driver behaves weirdly when using napi_gro_receive.

For example downloading a big file from a local network (low ping) is
fast, but when downloading from a remote server (higher ping), the
download speed is at first high but drops rapidly to almost nothing or
absolutely nothing.

This is fixed when using netif_receive_skb instead of napi_gro_receive.

Before doing this, we should really understand what is going on. It is
probably just a driver bug which needs fixing. And GRO should be good
for performance, so we do want to use it, if possible.
