[PATCH net-next 8/9] ks8695net: add GRO support

[Eric Dumazet]

Use napi_complete_done() instead of __napi_complete() to :

1) Get support of gro_flush_timeout if opt-in
2) Not rearm interrupts for busy-polling users.
3) use standard NAPI API.

Note that rx_lock seems to be useless, NAPI logic should
not need this extra care.
