Hello Christoph,
Thanks for the answer. I do indeed have more general problems with
ROCEv2: ib_send_bw works fine for ROCEv1 but not with ROCEv2. I'm
going to follow with the Mellanox persons as it seems to be mlx4 or
configuration-related.

Hi Marta,

Do you run with RDMA-CM?
Can you please provide the command lines you use and the GIDs table?

Thanks

Marta

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?
