This is with a somewhat hacked 3.3.0-rc5+. Just
curious if this is a known problem.
Seems very reproducible on my system.

The warning means you're modifying an interface the driver doesn't (yet)
know about.
It's odd that you should be running into this on config_beacon() though
since that can only execute when the interface is up ... can you print
out the interface name in the warning?
This is still reproducible in 3.3.0-rc6+ from yesterday.
I create the VAP with this command:
./local/sbin/iw phy wiphy0 interface add vap0 type __ap
vap0: Failed check-sdata-in-driver check, flags: 0x0
That's it? That doesn't create a warning here, and somehow you're
running into nl80211_set_wiphy() which isn't called if you execute just
that iw command.
Well, there's a lot of other stuff going on too. Power is set, for one
thing, hostapd is started, etc.
I will see if I can come up with a easy way to reproduce this, but
it might be a few days as I'm stacked up with work at the moment.
Thanks,
Ben
