      mac80211: Extend the rate control API with an update callback · 81cb7623
      Sujith authored
      
      
      The AP can switch dynamically between 20/40 Mhz channel width,
      in which case we switch the local operating channel, but the
      rate control algorithm is not notified. This patch adds a new callback
      to indicate such changes to the RC algorithm.
      
      Currently, HT channel width change is notified, but this callback
      can be used to indicate any new requirements that might come up later on.

      mac80211: split IBSS/managed code · 46900298
      Johannes Berg authored
      
      
      This patch splits out the ibss code and data from managed (station) mode.
      The reason to do this is to better separate the state machines, and have
      the code be contained better so it gets easier to determine what exactly
      a given change will affect, that in turn makes it easier to understand.
      
      This is quite some churn, especially because I split sdata->u.sta into
      sdata->u.mgd and sdata->u.ibss, but I think it's easier to maintain that
      way. I've also shuffled around some code -- null function sending is only
      applicable to managed interfaces so put that into that file, some other
      functions are needed from various places so put them into util, and also
      rearranged the prototypes in ieee80211_i.h accordingly.

      mac80211: Re-enable aggregation · 8b30b1fe
      Sujith authored
      
      
      Wireless HW without any dedicated queues for aggregation
      do not need the ampdu_queues mechanism present right now
      in mac80211. Since mac80211 is still incomplete wrt TX MQ
      changes, do not allow aggregation sessions for drivers that
      set ampdu_queues.
      
      This is only an interim hack until Intel fixes the requeue issue.

      mac80211: rewrite HT handling · ae5eb026
      Johannes Berg authored
      
      
      The HT handling has the following deficiencies, which I've
      (partially) fixed:
       * it always uses the AP info even if there is no AP,
         hence has no chance of working as an AP
       * it pretends to be HW config, but really is per-BSS
       * channel sanity checking is left to the drivers
       * it generally lets the driver control too much
      
      HT enabling is still wrong with this patch if you have more than
      one virtual STA mode interface, but that never happens currently.
      Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be
      wrong, see the comment in ieee80211_enable_ht().
      
      Additionally, this fixes a number of bugs:
       * mac80211: ieee80211_set_disassoc doesn't notify the driver any
                   more since the refactoring
       * iwl-agn-rs: always uses the HT capabilities from the wrong stuff
                     mac80211 gives it rather than the actual peer STA
       * ath9k: a number of bugs resulting from the broken HT API
      
      I'm not entirely happy with putting the HT capabilities into
      struct ieee80211_sta as restricted to our own HT TX capabilities,
      but I see no cleaner solution for now.

      802.11: clean up/fix HT support · d9fe60de
      Johannes Berg authored
      
      
      This patch cleans up a number of things:
       * the unusable definition of the HT capabilities/HT information
         information elements
       * variable names that are hard to understand
       * mac80211: move ieee80211_handle_ht to ht.c and remove the unused
                   enable_ht parameter
       * mac80211: fix bug with MCS rate 32 in ieee80211_handle_ht
       * mac80211: fix bug with casting the result of ieee80211_bss_get_ie
                   to an information element _contents_ rather than the
                   whole element, add size checking (another out-of-bounds
                   access bug fixed!)
       * mac80211: remove some unused return values in favour of BUG_ON
                   checking
       * a few minor other things
