[PATCH 3/7] libibumad: Add basic SM definitions to umad

sean.hefty-ral2JQCrhuEAvxtiuMwx3w
2013-01-28T21:38:51Z

From: Sean Hefty <sean.hefty-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

Add a new header file, umad_sm.h, to libibumad that contains
basic SM MAD definitions.

Only the SM attributes values, new methods, and base SM MAD
format are given. SM attribute structure definitions are
left for future development.
