Subject: [PATCH net-next 2/2] r8152: adjust rtl_start_rx
Date: Fri, 7 Nov 2014 17:55:11 +0800 [thread overview]
Message-ID: <1394712342-15778-90-Taiwan-albertk@realtek.com> (raw)
In-Reply-To: <1394712342-15778-88-Taiwan-albertk@realtek.com>
Submit all the rx buffers, even though a error occurs. Otherwise
the buffers which are not submitted would be lost until next
rtl_start_rx() is called. Besides, the fail buffer could be
re-submitted later.
