[dpdk-dev] [PATCH v8 1/4] lib/ether: optimize struct rte_eth_tunnel_filter_conf

[Jingjing Wu <jingjing.wu@intel.com>]

From: Xutao Sun <xutao.sun@intel.com>

Change the fields of outer_mac and inner_mac in struct
rte_eth_tunnel_filter_conf from pointer to struct in order to
keep the code's readability.
