Subject: [RFC PATCH net-next 6/9] net: dsa: remove the transactional logic from VLAN objects
It should be the driver's business to logically separate its VLAN
offloading into a preparation and a commit phase, and some drivers don't
need / can't do this.
So remove the transactional shim from DSA and let drivers to propagate
errors directly from the .port_vlan_add callback.
