If it matters may be the state can be saved?  On restart
wpa_supplicant can use it as a hint.

The problem seems to be generic in that suspend/resume needs
to save more state than shutdown/boot (or may be, the only
difference between the two is state saving).

You mean targets like suspend/resume?

Not sure if you guys need me to test anything....

Thanks for looking into this!
