Basically cleaning ib_types.h issue (which was raised repeatedly in the
past too) and making some order here with libibmad duplications would be
a nice thing.

However I still not understand clearly yet how things should be
organized properly (assumig all histories, ibutils dependencies, etc.).
And sure we can try to find an optimal model, so let's discuss:

libibumad is an option. However today this library only provides a
layer to user_mad kernel API and actually is transparent to MAD's
structure. Maybe complicating this with adding ib_types.h and some MAD
fields access helpers is not a big deal, but sort of disadvantage
anyway.

To place this stuff in separate library/package is another possibility,
but perspective of adding new package doesn't make me happy.

In theory ib_types.h would be also merged with libibmad. However for
me the current libibmad seems to be too much heavy for not using it for
stuff other than infiniband-diags.

Another options?

Now I likely would agree with Ira that moving ib_types.h to libibumad
is a least painful option. Do we have a better ideas?
