Checking if the controller is enabled (CC.EN == 1) is now done without
blocking.
Additionally, a copy of the controller configuration register (CC) value
is now stored in spdk_nvme_ctrlr.process_init_cc. It'll be updated in
subsequent patches whenever the register is written / read. This will
make it possible to make several function non-blocking without having

John Kariuki tested this patch on a system with

performance impact of adding these two
spdk_trace_records() in the main NVMe I/O path.
The pathological case (512B random reads on a single
Xeon core) decreased from 13.10M to 12.88M, or 1.7%.
Normal workloads (4KB+) would incur a smaller penalty
since the I/O rate would be much lower - maybe even
unnoticeable..
This is a really valuable tracepoint to have enabled
by default, so I think this small amount of degradation
is acceptable.

This new API signals that the ctrlr will soon be
reset. This allows the transport to skip unnecessary
steps in following calls to the driver prior to the
reset - for example, skipping PCIe DELETE_SQ/CQ
commands when freeing an IO qpair.
Note that if we are deleting a qpair after
prepare_for_reset was called, and the qpair is
still waiting for a CREATE_IO_CQ or CREATE_IO_SQ,
we cannot poll for those commands to complete,
but we also cannot free the qpair immediately.
So set a flag for this case to defer the
destruction until the outstanding CREATE_IO_CQ or
CREATE_IO_SQ callback is invoked (typically as an
aborted command when the reset happens).

The pcie layer can't always detect bad addresses
in the request at submission time - for example,
the transport may not have any trackers available
and the request gets queued at the generic
nvme level.
So this means that we might detect vtophys failures
during submission time, or in a process_completions
context - the latter happening when we complete
one request which triggers submitting a new request.
Currently if the vtophys failure happens during
submission context, we return -EFAULT to the
caller *and* call the completion callback. Nowhere
else in the driver do we do both - the intention
has always been that you get one or the other.
So make all of this consistent by tagging the
tracker and the qpair with a flag if we hit a vtophys
error in the submission path. Return 0 to the caller,
who will then later get a completion callback for the
bad request when the qpair is next processed for
completions.
I considered a separate TAILQ to hold these 'bad'
trackers, but that would have required duplicating
quite a bit of the tracker completion code for this
one case. The flag on the pqpair is already in the
hot cacheline, so it's cheap to check it. We will
only interate the outstanding_tr list when that flag
is set, so this should have zero impact to performance.
Fixes issue #2085.

Previously this was assumed to be a synchronous process so the generic
layer transport code updated the state after .ctrlr_connect_qpair
returned. In preparation for making this support asynchronous mode,
shift that responsibility down into the individual transports.
While none of the transports actually do this asynchronously, insert a
busy wait in nvme_transport_ctrlr_connect_qpair to wait for the qpair to
exit from the CONNECTING state. None of the upper layer code can
actually correct handle a transport doing this asynchronously, so the
busy wait will cover that.

nvme_cuse.c: 654:cuse_ctrlr_ioctl: *ERROR*: Unsupported IOCTL 0x4E40.
get-namespace-id: Invalid argument
The reason is because nvme-cli now also sends NVME_IOCTL_ID to the
target device to determine if it's indeed a controller or a ns. In
case kernel returns ENOTTY then nvme-cli considers the device to be
a controller. Since cuse_ctrlr_ioctl() returns EINVAL in such a case
the nvme-cli fails.
To avoid this simply replace EINVAL with ENOTTY for the ioctls that

Fixes#2022
If queued aborts are present when trying to fail a ctrlr
using spdk_nvme_ctrlr_fail(), then the abort command completion
will attempt to retry one of the queued aborts.
This eventually leads to a segfault that can be avoided by not
retrying any queued aborts.

After correct trstring initialization, it is
overwritten with trstring value of the current
probe ctx. That leads to a problem when initiator
connects to a sbusystem with listeners of different
transport types (e.g. TCP and RDMA). If probe_ctx has
TCP type, than discovery probe initialized probe trid
with trtype=RDMA and trstring=TCP. As results, SPDK
creates TCP controller with trtype=RDMA and we hit
assert in nvme_tcp_qpair function.

This update will allow us to use spdk_nvme_detach_async() and
spdk_nvme_detach_poll_async() easier to aggregate multiple detachments.
Previously, we could do:
spdk_nvme_detach_async()
spdk_nvme_detach_async()
spdk_nvme_detach_async()
and then started doing spdk_nvme_detach_poll_async().
Hence aggregating multiple detachments is already supported.
After this patch, the following sequence is possible:
spdk_nvme_detach_async() = 0
spdk_nvme_detach_async() = 0
spdk_nvme_detach_async() = 0
spdk_nvme_detach_poll_async() = -EAGAIN
spdk_nvme_detach_async() = 0
spdk_nvme_detach_async() = 0
spdk_nvme_detach_poll_async() = -EAGAIN
spdk_nvme_detach_poll_async() = -EAGAIN
spdk_nvme_detach_poll_async() = -EAGAIN
spdk_nvme_detach_poll_async() = 0
The actual changes is to remove the variable polling_started from
struct spdk_nvme_detach_ctx because it is not necessary anymore.
Clarify this change via updating the header file and CHANGELOG.
Verify this change by unit test.

SPDK_NVME_ASYNC_EVENT_NS_ATTR_CHANGED).
But actually not.
Since for SPDK, when target sent the non-first event, the condition
"nvmet_aen_bit_disabled(ctrl, NVME_AEN_BIT_NS_ATTR)" that prevents
target from sending event was matched.
This commit fix this issue by issuing a get_log_page cmd for each async

We map the SPDK_NVME_TRANSPORT_* values directly to
the NVMe-oF trtype values. Since PCIe isn't
Fabrics, we choose 256 which is outside of the
8-bit trtype range of values.
So we can just check if trtype >= 256 to determine
if the trid is for fabrics or not. This is
preferable to checking PCIE || VFIOUSER in case
additional non-fabrics transport types are added
in the future.
I considered taking a trid as the parameter instead,
but went this route since it is consistent with
the existing spdk_nvme_ctrlr_is_discovery().

Connect the adminq as part of controller initialization
instead of controller construction.
We never actually 'connected' the adminq for
PCIe or vfio-user transports, since its a nop.
But their connect_qpair transport ops function
is also a nop for the adminq, so it's fine to
generically connect the adminq across all transports.
Note that we cannot read registers (cc or csts)
during controller initialization now until after
the adminq has been connected since reading fabrics
registers depends on a connected adminq. This gets
special cased for now, but eventually reading
cc and csts will need to be part of the state machine
itself to make it asynchronous.
