Sean Hefty is upstream for librdmacm and he should have a git repo under
his name.  OFED pretty much takes his stuff unmodified, so there is no
specific OFED repo for librdmacm.  There are other things OFED pulls
unmodified too, so it's not that they change all the packages they
include, just some.  However, there are actually a few things that only
come from OFED and don't have their own repo or tarball release outside
of their tarball in the larger OFED tarball.  In those cases I have to
grab it from OFED, sometimes modify it to work with pristine upstream,
then package that up (qperf is an example, it's written to work with
OFED libibverbs and assumes that is what it's compiled against, so I had
to back out XRC support from day one to make it work with upstream
libibverbs...they didn't even bother to conditionalize XRC support in
qperf prior to it being accepted upstream in libibverbs).
