I explored /usr/src a bit to see where WITH_OFED actually comes into
play. For the most part, it appears to be just adding the following to
the build tree:
/usr/src/contrib/ofed
/usr/src/sys/ofed
Outside the ofed directories and the kernel, it doesn't seem to do a
lot, as I would expect.
/usr/src/etc/rc.d/Makefile optionally builds opensm.
/usr/src/usr.bin/netstat/Makefile adds --DSDP to CFLAGS.
It would seem to me that it should be possible to build OFED userland
support without wasting time building the > 99% of the code that has
nothing to do with it.
Does anyone know of a proven method to build and install the OFED
userland without doing an entire buildworld?
This would go a long way toward easing deployment of the IB stack en masse.
I suspect that there would be stiff resistance to the idea of including
IB support in the default builds, since it would add some bulk and so
few people will ever use it. It may therefore be on those of us who are
interested in finding efficient ways to deploy IB support.

Jason
