I just hooked the hw scanning back up in iwlwifi (as of iwlwifi-0.0.14) The driver wasn't calling ieee80211_scan_complete() before to tell the stack the scan was done, so no results were being passing up.
Anyway, I ran a quick test of using hw_scan enabled and disabled on a system with 15 active and 17 passive channels.
hw scan: 2.2s
sw scan: 4.7s
So the SW scan wasn't the 10s that I stated before (although it sure felt like 10s before I ran it with 'time') But anyway... the hw scan is currently beating out sw scanning by ~54%, at least here.
