However, there is a reason why this switchdev API is counterproductive for a driver writer, and that is because although br_switchdev_set_port_flag gets passed a "flags" and a "mask", those are passed piecemeal to the driver, so while the PRE_BRIDGE_FLAGS listener knows what changed because it has the "mask", the BRIDGE_FLAGS listener doesn't, because it only has the final value. This means that "edge detection" needs to be done by each individual BRIDGE_FLAGS listener by XOR-ing the old and the new flags, which in turn means that copying the flags into a driver private variable is strictly necessary. This can be solved by passing the "flags" and the "value" together into a single switchdev attribute, and it also reduces some boilerplate in the drivers that offload this.
