From: Gregory CLEMENT <gregory.clement@free-electrons.com>
Date: Wed, 9 Dec 2015 18:23:48 +0100
Subject: [PATCH] net: mvneta: Make the default queue related for each port
Instead of using the same default queue for all the port. Move it in the
port struct. It will allow have a different default queue for each port.
