[dpdk-dev] [PATCH v2 3/3] examples/ipsec-secgw: support IPv6 tunnel for lookaside proto

[Akhil Goyal]

IPv6 tunnels are already supported in case of inline and
lookaside none cases. In case of protocol offload, the details
for IPv6 header need to be added in session configuration
for security session create.
