generate 5GHz mac only for devices with 5GHz available #4
Description
App generates 5GHz mac for each and every device, which makes the list bigger than it need to be.
Would be good to have a check based on hardware model (nodeinfo.hardware.model) for that in the generating logic.
see e.g. https://github.com/MAGICCC/freifunk/blob/master/scripts/wifianalyzer_alias.py
Maybe the model list should not be hardcoded, but downloaded like domains.json,
so adding models would not lead to a new app release (e.g. resulting in a ./data/hardware.json).
