+Subject: 802.11: clean up/fix HT support
+
+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
+
