dpaa2-eth: Move DPAA2 Ethernet driver from staging to drivers/net

The DPAA2 Ethernet driver supports Freescale/NXP SoCs with DPAA2
(DataPath Acceleration Architecture v2). The driver manages
network objects discovered on the fsl-mc bus.

+ * struct dpni_queue - Queue structure
+ * @destination - Destination structure
+ * @destination.id: ID of the destination, only relevant if DEST_TYPE is > 0.
+ *	Identifies either a DPIO or a DPCON object.
+ *	Not relevant for Tx queues.
+ * @destination.type:	May be one of the following:
+ *	0 - No destination, queue can be manually
+ *		queried, but will not push traffic or
+ *		notifications to a DPIO;
+ *	1 - The destination is a DPIO. When traffic
+ *		becomes available in the queue a FQDAN
+ *		(FQ data available notification) will be
+ *		generated to selected DPIO;
+ *	2 - The destination is a DPCON. The queue is
+ *		associated with a DPCON object for the
+ *		purpose of scheduling between multiple
+ *		queues. The DPCON may be independently
+ *		configured to generate notifications.
+ *		Not relevant for Tx queues.
+ * @destination.hold_active: Hold active, maintains a queue scheduled for longer
+ *	in a DPIO during dequeue to reduce spread of traffic.
+ *	Only relevant if queues are
+ *	not affined to a single DPIO.
+ * @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.
