Heh. This is even more branding confusion that I think OpenFabrics as
an organization has not done well to clarify...
OpenFabrics Enterprise Distribution (OFED) is a) currently Linux-only,
and b) is a combined release mechanism / software package for several
different upper-level protocols (verbs, UDAPL, MPI, etc.) largely
employing RDMA-based technologies.
The "OFED" software is *not* the same thing as the verbs stack -- it
*includes* the verbs stack. For example, various Linux distros
include the verbs stack and some other RDMA-based packages (such as
Open MPI) but do *not* include OFED itself. OFED is basically
packaging and an installer/uninstaller for a whole bunch of
OpenFabrics-sponsored/related software packages.
For example, if you use the verbs stack on a RHEL distribution, it's
not OFED. It's the verbs that is packaged by RedHat. Same with
SuSE. Same with Debian. Same with ...etc.
So I think the name would be better as of-verbs.h, or openfabrics-
verbs.h, or ...

Ah -- I misunderstood.

Fair enough -- I have no problems #if LINUX'ing it for this release.
Mebbe someday if/when verbs is officially released on Solaris and
Windows and if we get adventurous enough, we can test on those
platforms and remove the #if LINUX protection. Cool?
