The firmware responding with -EBUSY when trying to add an extra virtual-if

Hi Hans,
First of all, sorry! This one is long overdue (thanks for the reminder, Kalle). Not sure what the claim is here. I have to check the firmware to see what could make this fail. Thing is that wpa_supplicant will try to create the interface upon startup and it is really required for P2P operations. Now people not using that will probably not care about the failure, but I would like to find out why it is failing. wpa_supplicant will not do a retry upon -EBUSY.
With which firmware (target string and version) are you seeing this so I know where to dive in.
