Johannes Berg says:
====================
My last pull request has been a while, we now have:
* connection quality monitoring with multiple thresholds
* support for FILS shared key authentication offload
* pre-CAC regulatory compliance - only ETSI allows this
* sanity check for some rate confusion that hit ChromeOS
(but nobody else uses it, evidently)
* some documentation updates
* lots of cleanups
====================
