nvme-rdma: add a NVMe over Fabrics RDMA host driver
This patch implements the RDMA host (initiator in SCSI speak) driver. It
can be used to connect to remote NVMe over Fabrics controllers over
Infiniband, RoCE or iWarp, and uses the existing NVMe core driver as well
a the new fabrics library.
To connect to all NVMe over Fabrics controller reachable on a given taget
port using RDMA/CM use the following command:
nvme connect-all -t rdma -a $IPADDR
This requires the latest version of nvme-cli with Fabrics support.
