Thanks for the ibv_get_devices()!!! I will go take a look at it. Below
you mentioned "spec", is there a spec for the
gen2 ibverbs? Or are you refering to the VAPI spec or the IBTA spec
chapter?
I've been assuming the code was the spec and that writing a specification
was still something that still needed to be
"contributed".

There are a couple of fairly large features that have not been
implemented at all, even in the kernel. For example, shared receive
queues (SRQ) and memory windows. Other than that I think libibverbs
support is pretty complete right now.
Of course the best thing is for application developers to ask for the
features they need. That way I don't waste time implementing
something that happens to be in the spec but no one cares about.
