| Subject: iwlwifi: dvm: fix D3 firmware PN programming |
| |
| 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. |
