net: introduce generic switch devices support The goal of this is to provide a possibility to support various switch chips. Drivers should implement relevant ndos to do so. Now there is only one ndo defined: - for getting physical switch id is in place. Note that user can use random port netdevice to access the switch.

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.

For DSA, the prepare phase is skipped and STP updates are only done in the commit phase. This is because currently the DSA drivers don't need to allocate any memory for STP updates and the STP update will not fail to HW (unless something horrible goes wrong on the MDIO bus, in which case the prepare phase wouldn't have been able to predict anyway).

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.

fib: hook IPv4 fib for hardware offload Call into the switchdev driver any time an IPv4 fib entry is added/modified/deleted from the kernel's FIB. The switchdev driver may or may not install the route to the offload device. In the case where the driver tries to install the route and something goes wrong (device's routing table is full, etc), then all of the offloaded routes will be flushed from the device, route forwarding falls back to the kernel, and no more routes are offloading. We can refine this logic later. For now, use the simplist model of offloading routes up to the point of failure, and then on failure, undo everything and mark IPv4 offloading disabled.
