Subject: Who should find out the initial frequency of IBSS join?

Hi,

I'm a total noob at this, but I'm trying to properly fix an issue I'm
having while joining an ad-hoc network with wpa_supplicant; nl80211:
Join IBSS failed. Specifying any frequency makes it work.

Apparently I'm not the only one that has had this issue, however the
fix I found is in NetworkManager[1], but there's a lot of people that
don't use NetworkManager. I tried to file a bug in wpa_supplicant [2],
but they don't think it's a problem there.

Although I think I might be able to write a fix in wpa_supplicant, I
wonder if it might make sense to do it in the nl80211 driver. Wouldn't
it be possible for the driver to check if there's no frequency, and
just try any that is supported?

Cheers.
