 *	Basically, this means that this queue can be used for any purpose
 * @IWL_MVM_QUEUE_RESERVED: queue is reserved but not yet in use
 *	This is the state of a queue that has been dedicated for some RATID
 *	(agg'd or not), but that hasn't yet gone through the actual enablement
 *	of iwl_mvm_enable_txq(), and therefore no traffic can go through it yet.
 *	Note that in this state there is no requirement to already know what TID
 *	should be used with this queue, it is just marked as a queue that will
 *	be used, and shouldn't be allocated to anyone else.
 * @IWL_MVM_QUEUE_READY: queue is ready to be used
 *	This is the state of a queue that has been fully configured (including
 *	SCD pointers, etc), has a specific RA/TID assigned to it, and can be
 *	used to send traffic.
 * @IWL_MVM_QUEUE_SHARED: queue is shared, or in a process of becoming shared
 *	This is a state in which a single queue serves more than one TID, all of
 *	which are not aggregated. Note that the queue is only associated to one
 *	RA.
 * @IWL_MVM_QUEUE_INACTIVE: queue is allocated but no traffic on it
 *	This is a state of a queue that has had traffic on it, but during the
 *	last %IWL_MVM_DQA_QUEUE_TIMEOUT time period there has been no traffic on
 *	it. In this state, when a new queue is needed to be allocated but no
 *	such free queue exists, an inactive queue might be freed and given to
 *	the new RA/TID.
 * @IWL_MVM_QUEUE_RECONFIGURING: queue is being reconfigured
 *	This is the state of a queue that has had traffic pass through it, but
 *	needs to be reconfigured for some reason, e.g. the queue needs to
 *	become unshared and aggregations re-enabled on.
