[nvme-fabrics]Fabrics over ROCEv2

[Christoph Hellwig]

Hi Marta,

we've tested the NVMe over Fabrics code with both Mellanox and Emulex
RoCE cards, although I don't remember if we were using RoCEv2.

But your problem doesn't sound NVMe specific.  Can your first check if a
simple test using ib_send_bw works?
