[Bridge] [PATCH net-next 09/16] switchdev: Add SWITCHDEV_PORT_ATTR_SET

[Florian Fainelli <f.fainelli@gmail.com>]

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.
