+Subject: mac80211: fix debugfs lockup
+
+When debugfs_create_dir fails, sta_info_debugfs_add_work will not
+terminate because it will find the same station again and again.
+This is possible whenever debugfs fails for whatever reason; one
+reason is a race condition in mac80211, unfortunately we cannot
+do much about it, so just document it, it just means some station
+may be missing from debugfs.

+Subject: mac80211: fix HT information element parsing
+
+There's no checking that the HT IEs are of the right length
+which can be used by an attacker to cause an out-of-bounds
+access by sending a too short HT information/capability IE.
+Fix it by simply pretending those IEs didn't exist when too
+short.

+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

+Subject: mac80211: introduce hw config change flags
+
+This makes mac80211 notify the driver which configuration
+actually changed, e.g. channel etc.
+
+No driver changes, this is just plumbing, driver authors are
+expected to act on this if they want to.
+
+Also remove the HW CONFIG debug printk, it's incorrect, often
+we configure something else.

+Subject: mac80211: provide sequence numbers
+
+I've come to think that not providing sequence numbers for
+the normal STA mode case was a mistake, at least two drivers
+now had to implement code they wouldn't otherwise need, and
+I believe at76_usb and adm8211 might be broken.
+
+This patch makes mac80211 assign a sequence number to all
+those frames that need one except beacons. That means that
+if a driver only implements modes that do not do beaconing
+it need not worry about the sequence number.

+Subject: mac80211/drivers: rewrite the rate control API
+
+So after the previous changes we were still unhappy with how
+convoluted the API is and decided to make things simpler for
+everybody. This completely changes the rate control API, now
+taking into account 802.11n with MCS rates and more control,
+most drivers don't support that though.

+This patch enhances minstrel's performance for non-MRR setups,
+by preventing it from sampling slower rates with >95% success
+probability and by putting at least 1 non-sample frame between
+several sample frames.
