Subject: [PATCH net-next 3/8] net: dsa: Handle SWITCHDEV_PORT_ATTR_SET
Date: Fri, 22 Feb 2019 15:59:21 -0800	[thread overview]
Message-ID: <20190222235927.10295-4-f.fainelli@gmail.com> (raw)
In-Reply-To: <20190222235927.10295-1-f.fainelli@gmail.com>

Following patches will change the way we communicate setting a port's
attribute and use notifiers towards that goal.

Prepare DSA to support receiving notifier events targeting
SWITCHDEV_PORT_ATTR_SET from both atomic and process context and use a
small helper to translate the event notifier into something that
dsa_slave_port_attr_set() can process.
