Although the sysfs interface is deprecated and should not be extended if new options are added. There are still users and admins use this interface to config bridge options. It would help users to know what the meaning of each field. Add correspond netlink enums (as we have document for them) for bridge sysfs attributes, so we can use it in Documentation/networking/bridge.rst.
