The fact that the tagging protocol is set and queried from the /sys/class/net/<dsa-master>/dsa/tagging file is a bit of a quirk from the single CPU port days which isn't aging very well now that DSA can have more than a single CPU port. This is because the tagging protocol is a switch property, yet in the presence of multiple CPU ports it can be queried and set from multiple sysfs files, all of which are handled by the same implementation. The current logic ensures that the net device whose sysfs file we're changing the tagging protocol through must be down. That net device is the DSA master, and this is fine for single DSA master / CPU port setups. But exactly because the tagging protocol is per switch [ tree, in fact ] and not per DSA master, this isn't fine any longer with multiple CPU ports, and we must iterate through the tree and find all DSA masters, and make sure that all of them are down.
