Are there any plans on providing this information from all channels? I
have assumed that the survey command was supposed to be used for
surveying all channels (e.g., to get information for auto-channel
selection) and returning something for the current channel is quite
limited subset of that. In other words, I would like to be able to run a
scan of all channels and then use NL80211_CMD_GET_SURVEY to fetch
additional per-channel information like noise (and also channel usage
statistics in case of ath9k) from the scanned channels.
