-I read a bit through the code and found one thing which explains
-both the issue and the random reproducibility behaviour in
-comment 14 and 16.  Currently I can't reboot to fully confirm,
-only did the speed test as in comment 16. (After overhight
-hibernate I'm back to the state as in comment 14.)
-
-This one change on top of v3.16 seems to fix it.
-
-Another thing caught my eye, it is unrelated to this bug but
-I'm reporting it here for my convenience ;-)
-In ath9k_cmn_rx_skb_postprocess():
-

-        fc = hdr->frame_control;
-        padpos = ieee80211_hdrlen(fc);

-Now padpos == hdrlen, except ieee80211_get_hdrlen_from_skb()
-checks the skb->len and might fail.  This is confused.  If the
-skb->len check is needed, shouldn't it be done before calling

+Subject: Input: xpad - add support for Xbox One controllers
+
+Xbox One controllers require an initialization message to start sending
+data, so xpad_init_output becomes a required function. The Xbox One
+controller does not have LEDs like the Xbox 360 controller, so that
+functionality is not implemented. The format of messages controlling rumble
+is currently undocumented, so rumble support is not yet implemented.
+
+Note that Xbox One controller advertises three interfaces with the same
+interface class, subclass and protocol, so we have to also match against
+interface number.
