The probe-request template used in the hardware connection monitoring feature thus far has been an empty one, without the SSID IE and without supported rate IEs. This causes problems with some AP's. Additionally, after connected scans, the template for connection maintenance would remain to be the one last used for scanning - potentially incorrect. Fix these by getting a pre-filled directed probe-request template for the associated-to AP from mac80211.
