Subject: [PATCH net v2 8/9] r8152: avoid the MCU to clear the lanwake
Date: Wed, 22 Jan 2020 09:41:20 +0800 [thread overview]
Message-ID: <1394712342-15778-356-Taiwan-albertk@realtek.com> (raw)
In-Reply-To: <1394712342-15778-348-Taiwan-albertk@realtek.com>
Avoid the MCU to clear the lanwake after suspending. It may cause the
WOL fail. Disable LANWAKE_CLR_EN before suspending. Besides,enable it
and reset the lanwake status when resuming or initializing.

Subject: [PATCH net-next 6/6] r8152: search the configuration of vendor mode
Date: Fri, 16 Apr 2021 16:04:37 +0800 [thread overview]

Message-ID: <20210416080437.tUQmdAuT5siG_YTEGbg0tJOo-NUQElOZeHliZX095Tg@z> (raw)
In-Reply-To: <1394712342-15778-350-Taiwan-albertk@realtek.com>
The vendor mode is not always at config #1, so it is necessary to
set the correct configuration number.
