Hi Daniel, >> Internally it might do that, but I do not see it exposing the >> NL80211_ATTR_MAC when you get the attributes for wiphy. > > When wlan0 is created, it can be created with its own MAC irrespective > of the wiphy MAC.

And that is actually just a number. So I have no idea what the MAC has to here. >> So I am still saying that when you do NL80211_CMD_NEW_INTERFACE allow >> providing NL80211_ATTR_MAC to set the MAC address to be used.

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?
