      mac80211: add time synchronisation with BSS for assoc · 8c358bcd
      Johannes Berg 提交于
      Some drivers (iwlegacy, iwlwifi and rt2x00) today use the
      bss_conf.last_tsf value. By itself though that value is
      completely worthless since it may be ancient. What really
      is needed is synchronisation between some device time and
      the TSF.
      
      To clarify this, rename bss_conf.last_tsf to sync_tsf and
      add sync_device_ts which is obtained from rx_status which
      gets a new field device_timestamp for this purpose. This
      is intentionally not using the mactime field since that
      is used for other things and in IBSS is expected to sync
      with the IBSS's TSF which isn't necessarily true for the
      device timestamp.
      
      Also, since we have the information and it's useful even
      before the connection has been established, give all the
      timing details to the driver before authenticating.
