Detailed Description

struct data_queue: Data queue

: Pointer to main &struct rt2x00dev where this queue belongs to. : Base address of the &struct queue_entry which are part of this queue. : The queue identification, see &enum data_queue_qid. : Entry flags, see &enum queue_entry_flags. : The mutex for protecting the start/stop/flush handling on this queue. : Spinlock to serialize tx operations on this queue. : Spinlock to protect index handling. Whenever , or needs to be changed this lock should be grabbed to prevent index corruption due to concurrency. : Number of frames handled in the queue. : Maximum number of entries in the queue. : Minimum number of free entries before queue is kicked by force. : Number of frames in queue. : Index pointers to entry positions in the queue, use &enum queue_index to get a specific index field. : maximum burst time. : The aifs value for outgoing frames (field ignored in RX queue). : The cw min value for outgoing frames (field ignored in RX queue). : The cw max value for outgoing frames (field ignored in RX queue). : Maximum data size for the frames in this queue. : Hardware descriptor size for the data in this queue. : Device endpoint used for communication (USB only) : Max packet size for given endpoint (USB only)
