Subject: [PATCH net v2 3/4] r8152: re-schedule napi for tx
Date: Wed, 25 Jan 2017 16:13:20 +0800 [thread overview]
Message-ID: <1394712342-15778-245-Taiwan-albertk@realtek.com> (raw)
In-Reply-To: <1394712342-15778-242-Taiwan-albertk@realtek.com>
Re-schedule napi after napi_complete() for tx, if it is necessay.
In r8152_poll(), if the tx is completed after tx_bottom() and before
napi_complete(), the scheduling of napi would be lost. Then, no
one handles the next tx until the next napi_schedule() is called.
