32a70c1ffc nvmf: Remove subsystem groups
This never really made sense, so replace it with a list of
subsystems.

b6af6bc6c1 test/nvmf: leave modules alone if already loaded
There's no benefit of reloading the NIC drivers (unless the drivers
themselves are buggy), so save some time by skipping the rmmod of
drivers we are about to load.

18ab3da5ad test/nvmf: clean up filesystem test
Inline function that is only called once.

Fix == bashism.

Create the filesystems on the partition created by parted rather than on
the raw namespace block device.

Add 'sync' invocations to make sure data gets flushed to the block
device we are testing.

Drop the copy-pasted FIO cleanup code (filesystem test does not run
FIO).

a9df326a0e nvmf: only allow one Controller per Subsystem
Multiple NVMe controllers within a subsystem does not work correctly,
since we would need to virtualize the controller data, namespace IDs,
and so on.  For now, only allow pass-through mapping of a single NVMe
controller per subsystem.

0e93df5c34 nvme: combine CAP register into one 64-bit union
Previously, we used cap_lo and cap_hi to represent the 32-bit halves of
the full CAP register.  However, it is simpler to keep them in a single
64-bit structure, and is no less efficient on 64-bit platforms.

Also name the NSSRS field from NVMe 1.2, which was previously reserved.

This should also help shorten the overall command line length that gets

eb555b139e nvme: add return code to nvme_qpair_submit_request
If the controller is failed, attempting to submit additional I/O is
futile - it will be immediately failed using the completion callback,
which can result in infinite recursion if the application code resubmits
I/Os on failure.

Instead, provide a way for request submission to indicate failure, and
use it to exit early if the controller is failed; this can only happen
when a reset failed (timed out).

If a request is submitted directly by the user when the controller has
failed, we can return an error code directly.  For the case where I/O
was queued and is being resubmitted after a reset, we still need to call
the completion handler via _nvme_fail_request_ctrlr_failed().

1dd7473078 nvme: create tracker pool in a single allocation
Replace the previous code that allocated each tracker individually with
one large allocation per queue pair.

struct nvme_tracker is now explicitly padded to reach exactly 4096 bytes
to allow normal array indexing to work correctly while maintaining the
alignment requirement that ensures each tracker's PRP list does not
cross a page boundary.

This also allows removal of the act_tr array, since the tr array can be
indexed directly now, and each tracker can store its own active state.

3272320c73 nvme: make I/O queue allocation explicit
The previous method for registering I/O queues did not allow the user
to specify queue priority for weighted round robin arbitration, and it
limited the application to one queue per controller per thread.

Change the API to require explicit allocation of each queue for each
controller using the new function spdk_nvme_ctrlr_alloc_io_qpair().

Each function that submits a command on an I/O queue now takes an
explicit qpair parameter rather than implicitly using the thread-local
queue.

This also allows the application to allocate different numbers of
threads per controller; previously, the number of queues was capped at
the smallest value supported by any attached controller.

Weighted round robin arbitration is not supported yet; additional
changes to the controller startup process are required to enable
alternate arbitration methods.
