Subject: [PATCH net 1/3] r8152: disable MAC clock speed down
Date: Thu, 16 Jun 2016 10:55:17 +0800 [thread overview]
Message-ID: <1394712342-15778-180-Taiwan-albertk@realtek.com> (raw)
In-Reply-To: <1394712342-15778-179-Taiwan-albertk@realtek.com>
Disable MAC clock speed down. It may casue the first control
transfer to contain the wrong data, when the power state change
from U1 to U0.
