This is the first step in openfabrics support. I've also donelibibverbs, but need to check that. Let me know if someone else isworking on openfabrics.

Hi Dave,
We already have the netlink bindings under the name 'libnl', but itprobably doesn't install the Python bits. Can you adjust this patch toimprove the existing package?
We also have libibverbs in 'rdma-core'. I haven't tested thefunctionality of it, though.

Oops -- thanks! I'm puzzled how I missed libnl, in particular. I don'tknow whether the Python support is really worth it, but it's in theFedora rpm, and I'll try to fit it in.
I'd expect rdma-core in linux.scm not to be the userspace components,but then I'm also puzzled why I didn't find verbs with --search and itwas on Ludo's todo list. I'll look at psm support and libfabrics when Ihave a chance.
