the way I read the nl80211 code is that the NL80211_CMD_NEW_INTERFACE

OpenWrt finds a wiphy by its MAC.

Why does the wiphy need to know the MAC if it is always specified from
userspace when actually creating the new netdev interface. Works for
P2P devices, so why wouldn't it work for access point and station
mode?

A MAC can be specified for the netdev, but it is assigned to a wiphy
identified by its MAC.
