You have NFS v4 working, but not v3. Which do you want to use?

You should be able to use NFSv4 over RDMA with this command:

 mount -t nfs4 1.2.3.131:/ /mnt -i -o rdma,port=2050

I'm surprised to see that v3 doesn't work. If you'd like to get v3 
working, I can help you. Could you send me the following?

 cat /proc/fs/nfsd/versions 
 grep NFSD /your/kernels/.config
