    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.
