Ok, I had that in mind but could not see how to solve that.
The root problem is that the drive start associate when any of the
ieee80211_ioctl_siwessid() and ieee80211_ioctl_siwap() is called.
If the wpa_supplicant need call more than one of them the association start
I can see two ways to solve this:
1) Add an argument/flag to the ioctls above indicating if association should
2) Add a new ioctrl that initiate the association.
My patch above relies on that the wpa_supplicant always end the AP setup
with a ieee80211_ioctl_siwap().
