[openib-general] What is the correct method of determining the number of ports

[Kevin Reilly]

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.
