NFS RDMA on Ubuntu 15.10

Is there a way to setup NFS over RDMA using the Ubuntu 15.10 inbox driver?

I was able to get the server side up but cannot mount anything on the client side. I followed the instructions for the previous version from here:

HowTo Configure NFS over RDMA (RoCE) https://community.mellanox.com/s/article/howto-configure-nfs-over-rdma--roce-x

It seems that the mount utility does not have a ‘rdma’ option anymore? It gives me the ‘incorrect mount option’ error while mounting on the client side.

Thanks!

It might be good to check the subject with OS vendor and the reason why they removed this option. Just in case, if you already asked it, it could be nice to have a link to discussion here.
