Date: Wed, 29 Oct 2014 11:12:15 +0800 From: Hayes Wang <hayeswang@...ltek.com> To: <netdev@...r.kernel.org> CC: <nic_swsd@...ltek.com>, <linux-kernel@...r.kernel.org>, <linux-usb@...r.kernel.org>, Hayes Wang <hayeswang@...ltek.com> Subject: [PATCH net 1/3] r8152: clear SELECTIVE_SUSPEND when autoresuming The flag of SELECTIVE_SUSPEND should be cleared when autoresuming. Otherwise, when the system suspend and resume occur, it may have the wrong flow. Besides, because the flag of SELECTIVE_SUSPEND couldn't be used to check if the hw enables the relative feature, it should alwayes be disabled in close().
