| 24 | |
| 25 | This module (wlan_hdd_wmm.h interface + wlan_hdd_wmm.c implementation) |
| 26 | houses all the logic for WMM in HDD. |
| 27 | |
| 28 | On the control path, it has the logic to setup QoS, modify QoS and delete |
| 29 | QoS (QoS here refers to a TSPEC). The setup QoS comes in two flavors: an |
| 30 | explicit application invoked and an internal HDD invoked. The implicit QoS |
| 31 | is for applications that do NOT call the custom QCT WLAN OIDs for QoS but |
| 32 | which DO mark their traffic for priortization. It also has logic to start, |
| 33 | update and stop the U-APSD trigger frame generation. It also has logic to |
| 34 | read WMM related config parameters from the registry. |
| 35 | |
| 36 | On the data path, it has the logic to figure out the WMM AC of an egress |
| 37 | packet and when to signal TL to serve a particular AC queue. It also has the |
| 38 | logic to retrieve a packet based on WMM priority in response to a fetch from |
| 39 | TL. |
| 40 | |
| 41 | The remaining functions are utility functions for information hiding. |
