I will remove the deprecation notice and update the release notes.
Is it an ABI change instead of an API change?

This patch needs to include a documentation update in testpmd_funcs.rst.

I have checked testpmd_funcs.rst before.
The content in the testpmd_funcs.rst is: 

   testpmd> tunnel_filter add (port_id) (outer_mac) (inner_mac) (ip_addr) \
            (inner_vlan) (tunnel_type) (filter_type) (tenant_id) (queue_id)

It does not include the options, so I think I don't need to update this document.

Xutao

Sorry, I see your point now, that the tunnel/filter types are not being specified in the testpmd documentation.
But actually, I think it would be a good idea to enumerate the different types in that document as well
(and maybe add a description like "set fwd").

Plus, see one extra comment below.

Should be ipingre?

Doc for tunnel_filter is extended, and ipingre type is also mentioned here.
This part seems no relationship with the commit log "Change the fields of outer_mac
and inner_mac from pointer to struct in order to keep the code's readability".
It's better to move to latter patch.

You changed the value of in parameter.
It's better to use an internal variable to convert byte order.

Since this is the commit actually changing the ABI, its best to actually 
bump LIBABIVER right here as well lest it go forgotten, and also update 
the list of shared library versions in release notes.
See commit d8c4ae275582784ec0ff3b2c54a4c861b55bc056 for an example.

Oh and sorry for not noticing this earlier.

I didn't use the Macro "RTE_NEXT_ABI", so I think I don't need to update the shared library verisons.
And I also updated the doc about ABI change in the deprecation.rst and release notes.

Shared library version MUST change when there's an incompatible change 
to prevent programs/libraries linked against the older version to be 
used with the incompatible version, that is the sole reason for 
versioning the libraries in the first place. Whether RTE_NEXT_ABI is 
used or not is not relevant.

In fact RTE_NEXT_ABI creates a shared library version of its own, sort 
of parallel to the current one. The basic idea remains the same though: 
shared library version has to change when an incompatible change goes in.
