I notice you can get current cycle stats out of the pdev stats as well, and those update every time you ask firmware for stats. It won't be 100% accurate because you don't know when firmware was off-channel or not, but I guess it will be better for me than nothing. I certainly don't want to be scanning all the time, but grabbing firmware stats already happens when you get ethtool stats, so as long as I poll often enough to catch wraps, I think it will be good enough. I guess to get really accurate values, one would have to hack the firmware to keep its own accumulated stats and properly deal with channel changes.
