Running ASAP2

Hi. I want to run OVS-Offloads. I have a couple of ConnectX-4s back to back. Is there a guide on how to use ASAP? The closest thing to what I want is https://community.mellanox.com/docs/DOC-2641 but I am not able to access it. How do I get ASAP2 up and running?

Using MlxLink to Configure a Remote Ib Switch Through the Opensm Subnet Manager

One of the basic tenants of the open source community is to provide the community some access to query and to report bugs.
