knfsd: a transport driver for RDMA

These 15 patches are an experimental RDMA transport driver for knfsd. They have been tested quite extensively on 2.6.18, but less so on this latest version (2.6.21). The transport driver plugs into an earlier transport switch that Greg and Peter have since tuned up and posted here.
