From 6ad20165d376fa07919a70e4f43dfae564601829 Mon Sep 17 00:00:00 2001
From: Eric Dumazet <edumazet@google.com>
Date: Mon, 30 Jan 2017 08:22:01 -0800
Subject: drivers: net: generalize napi_complete_done()
napi_complete_done() allows to opt-in for gro_flush_timeout,
added back in linux-3.19, commit 3b47d30396ba
("net: gro: add a per device gro flush timer")
This allows for more efficient GRO aggregation without
sacrifying latencies.
