===== Notes =====


==== full-mac support ====
  * Need more capability info for card's supported features 
  * add request IEs to cfg80211_connected() & to nl80211 event 
  * add wpa version, cipher suites etc. from IW_AUTH to CONNECT cmd 
  * add cfg80211_register_netdev(netdev) 
  * add cfg80211_register_iwpriv(netdev, handlers) to support vendor drivers moving to cfg80211, MUST be done BEFORE cfg80211_register_netdev 
==== test mode ====
    * <code>   {
        .cmd = NL80211_CMD_TESTMODE,
        .dumpit = NULL,
        .doit = NULL,
        .policy = NULL,
        .flags = GENL_ADMIN_PERM,
   }</code>
    * testmode.dumpit = driver_ops.testmode_dumpit etc. 
    * no API rules 
    * compiled out by default, hard to enable, depends on CONFIG_DEBUG? 
    * small example tool in userspace? 
    * new multicast ID, nl80211_test_event(skb), maybe overwrite the CMD 
==== antenna settings ====
      * new antenna settings API needed 
==== rate control (and userspace API) ====
        * for debug: set of bitrates, legacy & ht (this is generic) 
        *  * optionally with _MAC attribute for per-station setting (e.g. for fixed links in a mesh) 
        *  * also export this information back in station info in nl80211 
        *   noop bitrate algorithm for TI 1271 chip 
        *   need generic HT rate algorithm 
        *   need simpler rate control algorithm due to CPU usage (PID?) 
        *   want API for switching algorithm, export list of names, select by name 
        *   stick with debugfs for more advanced per algo control/debug 
        *   we want to have multicast bitrate control (e.g. by looking through station list) 
        *   have allowed-multicast-rates bitmap 
        *   add ht bitrate reporting to GIWRATE, just export the speed 
==== wext deprecation ====
        *   * publish community statement that we no longer want wext 
==== action frame processing ====
        *     * receive action frame multicast group per interface 
        *     * use _FRAME attribute for the frames 
        *     * send action frame, TA verified in cfg80211 
        *     * commitment for handling action frames when mcast group is used 
        *     * restrict group to one process (is that even possible?) 
        *     * require extra commitment command, but commitment goes away once process dies, closes socket, unbinds mcast group 
        *     * frame should be buffered during scan 
        *     * (maybe later: location frame, add channel attribute in send cmd?) 
        *     * good capability handling for all of this 
        *     * filter (-EINVAL) when wrong frame is transmitted (e.g. != public-action before association, != action while associated...) 
==== channel stats/noise reporting ====
        *       * channel statistics (currently channel use, maybe noise floor later) 
        *       * add flag to request this while starting a scan 
        *       * remove iwconfig noise report 
==== ROAMING (moving within ESS) ====
        *         * good bg scan algorithm 
        *         * export roaming capabilities of driver/device combination (mac80211==none, iwm==full) 
        *         * link quality event? 
        *         *  * signal change 
        *         *  * packet loss 
        *         *  * rate going down 
        *         *  * beacon loss this needs configurable thresholds from userspace
