rte_flow update, following RFC [1], introduced frag_ext_exist field for IPv6 header item, used to indicate match on fragmented/non-fragmented packets. This patch updates testpmd CLI to support the new field.
To match on non-fragmented IPv6 packets, need to use pattern: ... ipv6 frag_ext_exist spec 0 frag_ext_exist mask 1 ... To match on fragmented IPv6 packets, need to use pattern: ... ipv6 frag_ext_exist spec 1 frag_ext_exist mask 1 ... To match on any IPv6 packets, the frag_ext_exist field should not be specified for match.
