Subject: [PATCH 05/12] net: mediatek: dropped rx packets are not being counted properly
Date: Sun, 5 Jun 2016 08:32:58 +0200 [thread overview]
Message-ID: <1465108385-38286-6-git-send-email-john@phrozen.org> (raw)
In-Reply-To: <1465108385-38286-1-git-send-email-john-Pj+rj9U5foFAfugRpC6u6w@public.gmane.org>
There are two places inside mtk_poll_rx where rx_dropped is not being
incremented properly. Fix this by adding the missing code to increment
the counter.
