The RSS expand function for IP-in-IP tunnel type is missed,
which leads to create following flow failed:
flow create 0 ingress pattern eth / ipv4 proto is 4 /
ipv4 / udp / end actions rss queues 0 1 end level 2
types ip ipv4-other udp ipv4 ipv4-frag end /
mark id 221 / count / end
In order to make RSS expand function working correctly,
now the way to check whether a IP tunnel existing is to
check whether there is the second IPv4/IPv6 item and whether the
first IPv4/IPv6 item's next protocl is IPPROTO_IPIP/IPPROTO_IPV6.
For example:
... pattern eth / ipv4 proto is 4 / ipv4 / ....
