* 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()

* 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
