Merge branch 'mlxsw-IPIP-cleanups'

Jiri Pirko says:

====================
mlxsw: IPIP cleanups

In the first patch, a forgotten #include is added. Even though the code
compiles as-is, the include is necessary for modules that should include
spectrum_ipip.h.

The second patch corrects an assumption that IPv6 tunnels use struct
ip_tunnel_parm to store tunnel parameters.
