| * @IWL_MVM_DQA_P2P_DEVICE_QUEUE: a queue reserved for P2P device frames |
| * @IWL_MVM_DQA_INJECT_MONITOR_QUEUE: a queue reserved for injection using |

| * but we can't have active monitor mode along with P2P device anyway. |
| * @IWL_MVM_DQA_GCAST_QUEUE: a queue reserved for P2P GO/SoftAP GCAST frames |
| * @IWL_MVM_DQA_BSS_CLIENT_QUEUE: a queue reserved for BSS activity, to ensure |
| * that we are never left without the possibility to connect to an AP. |
| * @IWL_MVM_DQA_MIN_MGMT_QUEUE: first TXQ in pool for MGMT and non-QOS frames. |
| * Each MGMT queue is mapped to a single STA |
| * MGMT frames are frames that return true on ieee80211_is_mgmt() |
| * @IWL_MVM_DQA_MAX_MGMT_QUEUE: last TXQ in pool for MGMT frames |
| * @IWL_MVM_DQA_AP_PROBE_RESP_QUEUE: a queue reserved for P2P GO/SoftAP probe |
| * responses |
| * @IWL_MVM_DQA_MIN_DATA_QUEUE: first TXQ in pool for DATA frames. |
| * DATA frames are intended for !ieee80211_is_mgmt() frames, but if |
| * the MGMT TXQ pool is exhausted, mgmt frames can be sent on DATA queues |
| * as well |
| * @IWL_MVM_DQA_MAX_DATA_QUEUE: last TXQ in pool for DATA frames |
