From mboxrd@z Thu Jan 1 00:00:00 1970 From: Neil Armstrong Subject: [RFC PATCH net-next 4/6] net: dsa: mv88e6060: use the correct bit shift for mac0 Date: Mon, 2 Nov 2015 11:57:22 +0100 Message-ID: <56374192.6040108@baylibre.com> Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Cc: linux-kernel@vger.kernel.org, "David S. Miller" , Florian Fainelli , Andrew Lunn , Guenter Roeck , Neil Armstrong , Vivien Didelot To: netdev@vger.kernel.org Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org According to the mv88e6060 datasheet, the first mac byte must be at position 9 instead of 8 since the bit 8 is used to select if the mac address must differ for each port for Pause frames. Use the correct shift and set the same mac address for all port.
