 * DQA queue numbers
 *
 * @IWL_MVM_DQA_CMD_QUEUE: a queue reserved for sending HCMDs to the FW
 * @IWL_MVM_DQA_AUX_QUEUE: a queue reserved for aux frames
 * @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
 *  monitor mode. Note this queue is the same as the queue for P2P device
 *  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
