Subject: [PATCH net-next 6/8] staging: fsl-dpaa2: ethsw: Handle SWITCHDEV_PORT_ATTR_SET
Date:   Fri, 22 Feb 2019 15:59:24 -0800
Message-Id: <20190222235927.10295-7-f.fainelli@gmail.com>
In-Reply-To: <20190222235927.10295-1-f.fainelli@gmail.com>
References: <20190222235927.10295-1-f.fainelli@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Following patches will change the way we communicate setting a port's
attribute and use a blocking notifier to perform those tasks.

Prepare ethsw to support receiving notifier events targeting
SWITCHDEV_PORT_ATTR_SET and simply translate that into the existing
swdev_port_attr_set() call.
