Subject: [RFC net-next 01/13] switchdev: Add SWITCHDEV_PORT_ATTR_SET, SWITCHDEV_PORT_ATTR_GET
Date:   Fri,  1 Feb 2019 14:06:45 -0800
Message-Id: <20190201220657.30170-2-f.fainelli@gmail.com>
In-Reply-To: <20190201220657.30170-1-f.fainelli@gmail.com>
References: <20190201220657.30170-1-f.fainelli@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In preparation for allowing switchdev enabled drivers to veto specific
attribute settings from within the context of the caller, introduce a
new switchdev notifier type for port attributes.
