Subject: [PATCH 16/33] can: rx-offload: can_rx_offload_offload_one(): increment rx_fifo_errors on queue overflow or OOM
Date: Tue, 5 Nov 2019 17:31:58 +0100 [thread overview]
Message-ID: <20191105163215.30194-17-mkl@pengutronix.de> (raw)
In-Reply-To: <20191105163215.30194-1-mkl@pengutronix.de>
If the rx-offload skb_queue is full or the skb allocation fails (due to OOM),
the mailbox contents is discarded.
This patch adds the incrementing of the rx_fifo_errors statistics counter.
