Definers are HW objects that are used for matching, rte items are
translated to definers, each definer holds the fields and bit-masks
used for HW flow matching.
This patch recognize IP-in-IP tunnel type in definer layer, including
the following combinations:
- IPv4 over IPv4
- IPv4 over IPv6
- IPv6 over IPv4
- IPv6 over IPv6
