Subject: [RFC net-next 13/13] net: switchdev: Replace port attr get/set SDO with a notification
Drop switchdev_ops.switchdev_port_attr_get and _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_GET and _SET.
Update switchdev_port_attr_get() to dispatch to this new function. Drop
__switchdev_port_attr_set() and update switchdev_port_attr_set()
likewise.
Signed-off-by: Florian Fainelli <f.fainelli@...il.com>
