On ia64, we get the following error in the OFED 1.5 build
(from e-mail: [ofa-general] ofa_1_5_kernel 20090618-0200 daily build status):

NFSRDMA: NFS backport for 2.6.22
This patch provides the NFS backport for 2.6.22. Since the RDMA
infrastructure does not work for this kernel release, only TCP
support has been tested. It passes Connectathon as a client and server.
