<p class="MsoNormal">I have tried everything I can to adjust params/caps/hints/flags, but it seems that the verbs provider doesn’t support rdma.<o:p></o:p></p>

<p class="MsoNormal">I considered using endpoint type RDM, but unfortunately, RDM is not supported by verbs either, and ep MSG not working any more with GNI (I only get “connection rejected” messages when I try it), so the two providers I’m targeting are mutually
incompatible – this is making development decisions difficult.<o:p></o:p></p>

<p class="MsoNormal">I’ve been going through the fabtests looking for one that will do RDMA and works, but using the verbs provider always fails</p>

<p class="MsoNormal">I updated both fabtests and libfabric from git master today or yesterday. (I’m sure endpoint MSG type was working on GNI previously, but it isn’t working for me now, should I go back to a fixed release sha in git?)<o:p></o:p></p>
