From: Johannes Berg <johannes.berg@intel.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 5bd166872d8f99f156fac191299d24f828bb2348 upstream.
The code to send the RX PN data (for each TID) to the firmware has a devastating bug: it overwrites the data for TID 0 with all the TID data, leaving the remaining TIDs zeroed. This will allow replays to actually be accepted by the firmware, which could allow waking up the system.
