Subject: [PATCH net-next 15/16] net: switchdev: Replace port attr set SDO with a notification
Date: Fri, 8 Feb 2019 16:32:47 -0800 [thread overview]
Message-ID: <20190209003248.31088-16-f.fainelli@gmail.com> (raw)
In-Reply-To: <20190209003248.31088-1-f.fainelli@gmail.com>
Drop switchdev_ops.switchdev_port_attr_set. Drop the uses of this field
from all clients, which were migrated to use switchdev notification in
the previous patches.
Add a new function switchdev_port_attr_notify() that sends the switchdev
notifications SWITCHDEV_PORT_ATTR_SET.
Drop __switchdev_port_attr_set() and update switchdev_port_attr_set()
likewise.
