I had a similar reaction as Hugh when I recently updated a kernel config from 4.14 to 4.15. I barely understand the kernel config options in question so I don't really know what is right or wrong. But it seems strange to me that when you turn off CFG80211_CERTIFICATION_ONUS in menuconfig that the options which get hidden are forced on. When options are hidden like this I assume (maybe incorrectly) that they are dependent on the option I just turned off and that the now hidden options will also be off. Kevin
