Using gcc version 4.8.5 20150623 (Red Hat 4.8.5-28), it reports the
following compiling error:
/download/dpdk/drivers/net/i40e/i40e_rxtx_vec_neon.c:175:65: error:
expected ';', ',' or ')' before 'rx_pkts' desc_to_ptype_v(uint64x2_t

/download/dpdk/drivers/net/i40e/i40e_rxtx_vec_neon.c:197:51: error:

*restrict rx_queue, struct rte_mbuf **restrict rx_pkts,
Fix this by using '__restrict' type qualifier, which compiles ok with
old and new versions of gcc.
