Re: I have problem porting my RDMA application from InfiniBand(Mellanox Connectx-3 40Gb IB) to RoCE(Connectx-4 100GbE).

Thanks Erez. Actually I found the solution later. It was a bug in my code. I didn't correctly set up the gid in the global routing header in queue attributes. After I fix that bug, it works perfectly.
