mac80211: sample survey implementation for mac80211 & hwsim
This adds the survey function to both mac80211 itself and to mac80211_hwsim. For the latter driver, we simply invent some noise level.A real driver which cannot determine the real channel noise MUST NOT report any noise, especially not a magically conjured one :-) Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: John W.
