Date: Fri, 2 Feb 2018 16:43:36 +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 2/2] r8152: set rx mode early when linking on Set rx mode before calling netif_wake_queue() when linking on to avoid the device missing the receiving packets. The transmission may start after calling netif_wake_queue(), and the packets of resopnse may reach before calling rtl8152_set_rx_mode() which let the device could receive packets. Then, the packets of response would be missed.
