Same comment applies here really...
+ * @noise: noise, as obtained from dump_survey of index 0.
It's not actually obtained that way, because if it was, cfg80211 could
just handle it by itself.
Additionally, even within mac80211 there's no guarantee that the
dump_survey(0) callback will give you the correct channel's noise.
Since you can easily obtain this information from userspace (and with
the extension that Felix proposed you can figure out which noise belongs
to the operating channel without really knowing the operating channel),
I don't think we should be doing this.
Do you have a pointer to Felix's proposal? Maybe I can use whatever API
he came up with to populate /proc/net/wireless with the noise from the current
channel.
Thanks,
