nvmf: Handle shutdowns more gracefully If an association is disconnected during a clean shutdown, abort all pending and future I/O requests with an error to avoid hangs either due to filesystem unmounts or a stuck GEOM event. If an association is connected during a clean shutdown, gracefully disconnect from the remote controller and close the open queues.

nvmf: Permit failing I/O requests while disconnected Add a kern.nvmf.fail_on_disconnection sysctl similar to the kern.iscsi.fail_on_disconnection sysctl. This causes pending I/O requests to fail with an error if an association is disconnected instead of requeueing to be retried once the association is reconnected. As with iSCSI, the default is to queue and retry operations. Reviewed by: imp Sponsored by: Chelsio Communications Differential Revision: https://reviews.freebsd.org/D45308

nvmf: The in-kernel NVMe over Fabrics host This is the client (initiator in SCSI terms) for NVMe over Fabrics. Userland is responsible for creating a set of queue pairs and then handing them off via an ioctl to this driver, e.g. via the 'connect' command from nvmecontrol(8). An nvmeX new-bus device is created at the top-level to represent the remote controller similar to PCI nvmeX devices for PCI-express controllers. As with nvme(4), namespace devices named /dev/nvmeXnsY are created and pass through commands can be submitted to either the namespace devices or the controller device. For example, 'nvmecontrol identify nvmeX' works for a remote Fabrics controller the same as for a PCI-express controller. nvmf exports remote namespaces via nda(4) devices using the new NVMF CAM transport. nvmf does not support nvd(4), only nda(4).
