  From: Junfeng Guo <junfeng.guo@intel.com>

1. Add profile rule for VXLAN on Switch Filter, including
	pattern_eth_ipv4_udp_vxlan_any
	pattern_eth_ipv6_udp_vxlan_any
	pattern_eth_ipv4_udp_vxlan_eth_ipv4
	pattern_eth_ipv4_udp_vxlan_eth_ipv6
	pattern_eth_ipv6_udp_vxlan_eth_ipv4
	pattern_eth_ipv6_udp_vxlan_eth_ipv6

2. Add common rule for VXLAN on Switch Filter, including

+-----------------+-----------------------------------------------------+
|     Pattern     |                    Input Set                        |
+-----------------+-----------------------------------------------------+
| ipv4_vxlan_ipv4 | vni, inner dmac, inner dst/src ip, outer dst/src ip |
| ipv4_vxlan_ipv6 | vni, inner dmac, inner dst/src ip                   |
| ipv6_vxlan_ipv4 | vni, inner dmac, inner dst/src ip                   |
| ipv6_vxlan_ipv6 | vni, inner dmac, inner dst/src ip                   |
