I don't think I'd do either of those. Not creating P2P_DEVICE will

So should we check that in cfg80211 upon wiphy_register().
Check what?
Check that the interface combinations contain a iface limit with only
P2P_DEVICE:
{
.max = 1,
.types = BIT(NL80211_IFTYPE_P2P_DEVICE)
}
I don't really see much choice but reject (or ignore) this option for
drivers using P2P_DEVICE. Why would anyone *really* want P2P operation
on wlan0 when another interface can be used?
In this mac80211_hwsim is a special case. We could make P2P_DEVICE
support in mac80211_hwsim optional using module parameter to allow
testing both cases.
Yes, that we could do.
