Denis Nagorny c273513401 nvme/rdma: Allows to use PCI Express Relaxed Ordering ... This fix allows to use relaxed ordering feature where it is supported. libibversb checks with the driver if relaxed ordering access flag is supported and ignores it if not. Experiments show that set by default it doesn't spoil performance but allows to reach desired one on AMD EPYC systems. For example fio read test (ConnectX-6, AMD EPYC 7763, two jobs, queue depth 32, block size 32K) can starve down to 6-7 GiB/s without it. Enabling this option allows to get bandwidth more than 21 GiB/s.
