Does this fix a visible bug? What changes from user space point of > view? I'm asking because I want to add something to the commit log. When user space requests survey info, it is useful to know which of the survey data refers to the channel that is currently actively being used. One of the use cases is getting the current channel noise for status output. Without this flag you would have to look up the channel separately and then compare it against the frequency in the survey output in user space. - Felix
