      wext: Emit event stream entries correctly when compat. · ccc58057
      David S. Miller authored
      Three major portions to this change:
      
      1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF,
         and IW_EV_COMPAT_POINT_LEN helper defines.
      
      2) Delete iw_stream_check_add_*(), they are unused.
      
      3) Add iw_request_info argument to iwe_stream_add_*(), and use it to
         size the event and pointer lengths correctly depending upon whether
         IW_REQUEST_FLAG_COMPAT is set or not.
      
      4) The mechanical transformations to the drivers and wireless stack
         bits to get the iw_request_info passed down into the routines
         modified in #3.  Also, explicit references to IW_EV_LCP_LEN are
         replaced with iwe_stream_lcp_len(info).
      
      With a lot of help and bug fixes from Masakazu Mokuno.

      mac80211: use hardware flags for signal/noise units · 566bfe5a
      Bruno Randolf authored
      trying to clean up the signal/noise code. the previous code in mac80211 had
      confusing names for the related variables, did not have much definition of
      what units of signal and noise were provided and used implicit mechanisms from
      the wireless extensions.
      
      this patch introduces hardware capability flags to let the hardware specify
      clearly if it can provide signal and noise level values and which units it can
      provide. this also anticipates possible new units like RCPI in the future.
      
      for signal:
      
        IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific
        IEEE80211_HW_SIGNAL_DB     - dB difference to unspecified reference point
        IEEE80211_HW_SIGNAL_DBM    - dBm, difference to 1mW
      
      for noise we currently only have dBm:
      
        IEEE80211_HW_NOISE_DBM     - dBm, difference to 1mW
      
      if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has
      to provide the maximum value (max_signal) it reports in order for applications
      to make sense of the signal values.
      
      i tried my best to find out for each driver what it can provide and update it
      but i'm not sure (?) for some of them and used the more conservative guess in
      doubt. this can be fixed easily after this patch has been merged by changing
      the hardware flags of the driver.
