a6dbe3721e update Intel copyright notices
per Intel policy to include file commit date using git cmd
below.  The policy does not apply to non-Intel (C) notices.

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the 4 digit year from the result.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc).  Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line.  Simply there for
consistency.

4300c62167 nvme: add spdk_nvme_ctrlr_disable_read_changed_ns_list_log_page()
Commit a119799b ("test/nvme/aer: remove duplicated changed NS list log")
changed the nvme driver to read the CHANGED_NS_LIST log page before
calling the application's AER callback (previously it would read it
after).

Commit b801af090 ("nvme: add disable_read_changed_ns_list_log_page")
added a new ctrlr_opts member to allow the application to tell the
driver to not read this log page, and will read the log page itself
instead to clear the AEN.  But we cannot add this option to the 22.01
LTS branch since it breaks the ABI.  So adding this API here, which
can then be backported manually to the 22.01 branch for LTS users
that require it.

Restoring the old behavior is not correct for applications that
want to consume the CHANGED_NS_LIST log page contents itself to
know which namespaces have changed.  Even if the driver reads the
log page after the application, that read could happen during a
small window between when a namespace change event has occurred and
the AEN has been sent to the host.  The only safe way for the
application to consume ChANGED_NS_LIST log page contents itself
is to make sure the driver never issues such a log page request
itself.

Fixes issue #2647.

this enables the application to tell the NVMe

c50cb569de include: add STATIC_ASSERTS for opts structures with size member
Various opts structures in SPDK have a size member, to enable
ABI compatibility should fields be added in the future.

But this requires the strucures to be packed, otherwise for
example a structure may be padded at the end, and a new
field added may just consume some of that padding.

So add STATIC_ASSERTS for the current sizes in this
patch.  Upcoming patches will make the structures packed
and add in reserved fields to fill in holes.

488570ebd4 Replace most BSD 3-clause license text with SPDX identifier.
Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file.  This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.

Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text.  There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".

Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

7a0a2800e0 nvme: Add three APIs for disconnect, start re-enable, and poll re-enable ctrlr
The NVMe bdev module will support two features, delayed reconnect and
delete after multiple failures of reconnect to improve error recovery.

The recently added two APIs, spdk_nvme_ctrlr_reset_async() and
spdk_nvme_ctrlr_reset_poll_async(), were not good enough.

spdk_nvme_ctrlr_reset_ctx was not necessary. It had only a pointer to ctrlr.
Using a pointer to ctrlr directly saves us from undesirable malloc error
processing.

Separate spdk_nvme_ctrlr_reset_async() into spdk_nvme_ctrlr_disconnect()
and spdk_nvme_ctrlr_reconnect_async(). spdk_nvme_ctrlr_disconnect()
disconnects ctrlr including disconnecting adminq.
spdk_nvme_ctrlr_reconnect_async() moves the ctrlr state to INIT.

Then rename spdk_nvme_ctrlr_reset_poll_async() by
spdk_nvme_ctrlr_reconnect_poll_async().

Finally deprecate spdk_nvme_ctrlr_reset_async() and
spdk_nvme_ctrlr_reset_poll_async().

The following patches will change the NVMe bdev module to use these new APIs.

This patch introduces asynchronous versions of the ctrlr_(get|set)_reg

doesn't make sense (e.g. PCIe), the transport layer will call the

3cb9bc2593 nvme: add spdk_nvme_ctrlr_prepare_for_reset()
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).

15b7d3bacc nvme/pcie: defer bad vtophys to completion context
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.

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().

3a58a5f19c nvme: add spdk_nvme_map_cmd API
The API `spdk_nvme_map_prps` is used in nvmf/vfio-user to
remap VM's NVMe command data buffer to local virtual address,
and for command using PRP, there maybe multiple pages, when
parsing the PRP list to local IOVs, we need a parameter to check
that the maximum number of vectors can't exceed the IOVs, this API
can't meet the requirement, while here, we add a new API `spdk_nvme_map_cmd`
and with a new parameter `max_iovcnt` to fix this case, and it can
also cover the command using SGL in the coming patches.
