Could the patch use the return value of ifup rather than grep'ing the ifstate 
file?

Also, this patch has the potential to bing back the "re-association storm" 
phenomenon that the wpa_hysteresis_{event,check} functions were designed to 
prevent. This could lead to an uncontrollable loop of failed re-association 
and failed ifup events.

Thanks, Kel.
