Subject: [PATCH net-next v2 2/2] r8152: add a helper function about setting EEE
Date: Fri, 23 Aug 2019 15:04:12 +0800 [thread overview]
Message-ID: <1394712342-15778-307-Taiwan-albertk@realtek.com> (raw)
In-Reply-To: <1394712342-15778-305-Taiwan-albertk@realtek.com>
Add a helper funtcion "rtl_eee_enable" for setting EEE. Besides, I
move r8153_eee_en() and r8153b_eee_en(). And, I remove r8152b_enable_eee(),
r8153_set_eee(), and r8153b_set_eee().
