Regarding sched scan, I think the more correct behavior is to restart sched scan whenever the enabled networks list change (e.g. enable/disable/remove) as otherwise we'd continue to sched scan a non relevant list of SSIDs. This would also take care of removing all networks given that we bail out in wpa_supplicant_req_sched_scan if there aren't any enabled networks. I have some internal patches on our tree doing something like this but they need some work to be rebased on the latetest master. If we agree that's a better approach I can rebase them and submit.
About scan - you are right, but I did it just to be clear here. Regarding sched scan, I did think about this option. I'm not sure it's better to reschedule scan wherever network list is changed, because maybe it's better to send some redundant probe requests than rescheduling new scan. If you still think rescheduling is better, so go ahead with your patch when removing or disabling a network. In case of enabling there is other my patches.

Sending 16 probes (in case of our maximal 16 SSIDs it's actually even 32 as each one is transmitted twice) vs. just 1 has an impact on power (due to additional Tx as well as longer dwell time we set in case there are more probes). That's why I think it's good to restart the sched scan. About enable - yep, you handle it already correctly.

Just to confirm I understood the thread correctly.. I'm assuming this is referring to the full set (three patches) instead of just 1/3. I'm currently waiting for the alternative patch before applying any of these.
