I don't understand the last sentence, please elaborate.

IMHO the help text still contains too much Intel jargon to be really understandable by everyone. I think the commit log pretty well summarises what this is all about: "CSME stands for Converged Security and Management Engine. It is a CPU on the chipset and runs a dedicated firmware. AMT (Active Management Technology) is one of the applications that run on that CPU. AMT allows to control the platform remotely." Somehow including that information to the Kconfig help text would be very helpful to everyone. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
