The issue is with Fast Reg WR, which are needed to setup a NFS RDMA connection.  The issue is that the 2.6.0 firmware advertises support for this feature (previous versions did not), but there is bug in the firmware.    2.7.0 firmware resolved this issue.  Bug 1815 hit this issue, and the originator suggested I document the "fix" in the OFED docs.

If the verbage is confusing, I can reduce it to say that ConnectX requires 2.7.0 firmware for NFSRDMA.

Thanks,
Jon
