I'm not sure about that.
One thing that I'm sure of is that for the Libertas case I need to scan
*before* the connection takes place. The Libertas firmware doesn't roam by
itself, so I don't tell her an SSID like you'll tell the orinoco firmware.
Instead the libertas firmware needs a BSSID where it should connect to. If
you let do wpa_supplicant do the job (even for WEP), that's no problem,
because wpa_supplicant always scans and then connects to a specific BSSID,
which suits Libertas very well.
As for sending back then cfg80211_connect_result() to cfg80211, I'm using
the IEs from the firmware CMD_802_11_ASSOCIATE command, which seems to work
quite nicely.
The only thing where Libertas would need a scan during connect if someone
tries to connect to an AP without a previous scan using the "iw wlan0
connect" command. Not sure what Simon did here, but my previous v4 patch
simply failed.
