Yes, my mistake, I was talking about wpa_s->config->ssid.

Afaik, nothing prevents you from using wpa_s->config->ssid for you own 
purpose (back-upping it, providing you own etc...).
But since it's not that clean, I will add a struct 
wpa_driver_scan_params *autoscan_params in wpa_s that you could set in 
the module.
In req_scan/req_sched_scan function: if that pointer is set it would 
directly use it.

This solution is a bit more intrusive, but way much less than managing 
everything in the module as you proposed,
and solves you issue fully since you can tweak completely the scan 
params then.

I will prepare a new patch set.

Br,

Tomasz
