Regarding testing of NFS over RDMA patch on AMMASO RNIC.

[James Lentini]

Thank you for the logs Siva.

In fs/nfsd/nfssvc.c:nfsd_svc(), there should be a call to 
svc_makesock() under a CONFIG_NFSD_RDMA guard. Can you send that line 
of code?

I suspect that your client is attempting to connect to port 2049 and 
the server is listening on port 2050.
