* @flist: pointer to list of the free slots associated with queue

*
* This structure represents CAN FIFO queue. It is implemented as
* a single linked list of slots prepared for processing. The empty slots
* with ready messages. The array is indexed by the edges priorities.
* @idle: the list of the edges directed to the ends structure with empty FIFOs.
* @inlist: the list of outgoing edges input sides.
+ * @outlist: the list of all incoming edges output sides. Each of there edges
+ * is listed on one of @active or @idle lists.
* @ends_lock: the lock synchronizing operations between threads accessing
* same ends structure.
* @notify: pointer to notify procedure. The next state changes are notified.
