I don't think the way forward is using iba/ in all applications.
I see it mostly as a legacy header for opensm and related apps
that want their own layer for portability between stacks.

Wrt issue at hand, using ib_ prefix anywhere is a mistake which will always lead
to conflicts between libraries.  Let us start prefixing types libibumad defines
with umad_, just like ib verbs library prefixes types by ibv_.

For example we have union ibv_gid, so can't mad.h have umad_gid_t?

Hal, what do you say?
