- * @user_context: User data, presented to the user along with any frames
- * from this queue. Not relevant for Tx queues.
- * @flc: FD FLow Context structure
- * @flc.value: Default FLC value for traffic dequeued from
- * this queue. Please check description of FD
- * structure for more information.
- * Note that FLC values set using dpni_add_fs_entry,
- * if any, take precedence over values per queue.
- * @flc.stash_control: Boolean, indicates whether the 6 lowest
- * - significant bits are used for stash control.
- * significant bits are used for stash control. If set, the 6
- * least significant bits in value are interpreted as follows:
- * - bits 0-1: indicates the number of 64 byte units of context
- * that are stashed. FLC value is interpreted as a memory address
- * in this case, excluding the 6 LS bits.
- * - bits 2-3: indicates the number of 64 byte units of frame
- * annotation to be stashed. Annotation is placed at FD[ADDR].
- * - bits 4-5: indicates the number of 64 byte units of frame
- * data to be stashed. Frame data is placed at FD[ADDR] +
- * FD[OFFSET].
- * For more details check the Frame Descriptor section in the
- * hardware documentation.
