I'm more than happy to give this a thorough test on dozens of devices 
offshore

which I suspect are suffering from this issue as they sail in-out of range,

but as a new flag is defined in nl80211.h, is anything additional 
required at wpa_sup side to use this?

If yes, please also provide a patch for that to me directly. (based on 
 >= v2.9)

Thanks,
