With wpasupplicant 0.5.5-2 from debian and airo driver (wireless
extension) there is a race in the scan :
- the airo driver provides scan result only after 3 seconds
- the wpasupplicant expects scan result after 3 seconds and don't retry
in case of -EAGAIN.
In some condition wpasupplicant fails to scan.
The solution to resolve this is :
- increase wpasupplicant scan timeout to 4 (or more) seconds
- if the result is -EAGAIN after the timeout retry one (or more) times.
