So the problem is:
- hostapd requests master mode on "wlan0" using netlink,
- it gets to nl80211_set_interface(), drv->ops->change_virtual_intf(),
  ieee80211_change_iface() and then to ieee80211_if_change_type().

Then it fails with -EOPNOTSUPP.

int ieee80211_if_change_type(struct ieee80211_sub_if_data *sdata,
			     enum nl80211_iftype type)
{
	ASSERT_RTNL();

	if (type == sdata->vif.type)
		return 0;

	/* Setting ad-hoc mode on non-IBSS channel is not supported. */
	if (sdata->local->oper_channel->flags & IEEE80211_CHAN_NO_IBSS)
		return -EOPNOTSUPP;
                ^^^^^^^^^^^^^^^^^^^

The flags are set to 6 = IEEE80211_CHAN_NO_IBSS |
                         IEEE80211_CHAN_PASSIVE_SCAN

Unfortunately I don't know what does the above mean, except that
I don't want ad-hoc mode, I want AP instead.

Ideas?
