Scott Feldman 3094333d90 switchdev: introduce get/set attrs ops ... Add two new swdev ops for get/set switch port attributes. Most swdev interactions on a port are gets or sets on port attributes, so rather than adding ops for each attribute, let's define clean get/set ops for all attributes, and then we can have clear, consistent rules on how attributes propagate on stacked devs. Add the basic algorithms for get/set attr ops. Use the same recusive algo to walk lower devs we've used for STP updates, for example. For get, compare attr value for each lower dev and only return success if attr values match across all lower devs. For sets, set the same attr value for all lower devs. We'll use a two-phase prepare-commit transaction model for sets. In the first phase, the driver(s) are asked if attr set is OK. If all OK, the commit attr set in second phase. A driver would NACK the prepare phase if it can't set the attr due to lack of resources or support, within it's control. RTNL lock must be held across both phases because we'll recurse all lower devs first in prepare phase, and then recurse all lower devs again in commit phase. If any lower dev fails the prepare phase, we need to abort the transaction for all lower devs. If lower dev recusion isn't desired, allow a flag SWITCHDEV_F_NO_RECURSE to indicate get/set only work on port (lowest) device.
