+		 * The interactive process between software and hardware of
+		 * receiving a new packet in hns3 network engine:
+		 * 1. Hardware network engine firstly writes the packet content
+		 *    to the memory pointed by the 'addr' field of the Rx Buffer
+		 *    Descriptor, secondly fills the result of parsing the
+		 *    packet include the valid field into the Rx Buffer
+		 *    Descriptor in one write operation.
+		 * 2. Driver reads the Rx BD's valid field in the loop to check
+		 *    whether it's valid, if valid then assign a new address to
+		 *    the addr field, clear the valid field, get the other
+		 *    information of the packet by parsing Rx BD's other fields,
+		 *    finally write back the number of Rx BDs processed by the
+		 *    driver to the HNS3_RING_RX_HEAD_REG register to inform
+		 *    hardware.
+		 * In the above process, the ordering is very important. We must
+		 * make sure that CPU read Rx BD's other fields only after the
+		 * Rx BD is valid.
+		 *
+		 * There are two type of re-ordering: compiler re-ordering and
+		 * CPU re-ordering under the ARMv8 architecture.
+		 * 1. we use volatile to deal with compiler re-ordering, so you
+		 *    can see that rx_ring/rxdp defined with volatile.
+		 * 2. we commonly use memory barrier to deal with CPU
+		 *    re-ordering, but the cost is high.
+		 *
+		 * In order to solve the high cost of using memory barrier, we
+		 * use the data dependency order under the ARMv8 architecture,
+		 * for exmple:
+		 *      instr01: load A
+		 *      instr02: load B <- A
+		 * the instr02 will always execute after instr01.
+		 *
+		 * To construct the data dependency ordering, we use the
+		 * following assignment:
+		 *      rxd = rxdp[(bd_base_info & (1u << HNS3_RXD_VLD_B)) -
+		 *                 (1u<<HNS3_RXD_VLD_B)]
+		 * Using gcc compiler under the ARMv8 architecture, the related
+		 * assembly code example as follows:
+		 * note: (1u << HNS3_RXD_VLD_B) equal 0x10
+		 *      instr01: ldr w26, [x22, #28]  --read bd_base_info
+		 *      instr02: and w0, w26, #0x10   --calc bd_base_info & 0x10
+		 *      instr03: sub w0, w0, #0x10    --calc (bd_base_info &
+		 *                                            0x10) - 0x10
+		 *      instr04: add x0, x22, x0, lsl #5 --calc copy source addr
+		 *      instr05: ldp x2, x3, [x0]
+		 *      instr06: stp x2, x3, [x29, #256] --copy BD's [0 ~ 15]B
+		 *      instr07: ldp x4, x5, [x0, #16]
+		 *      instr08: stp x4, x5, [x29, #272] --copy BD's [16 ~ 31]B
+		 * the instr05~08 depend on x0's value, x0 depent on w26's
+		 * value, the w26 is the bd_base_info, this form the data
+		 * dependency ordering.
+		 * note: if BD is valid, (bd_base_info & (1u<<HNS3_RXD_VLD_B)) -
+		 *       (1u<<HNS3_RXD_VLD_B) will always zero, so the
+		 *       assignment is correct.
+		 *
+		 * So we use the data dependency ordering instead of memory
+		 * barrier to improve receive performance.
