38d59d8b5a nvme: add function to check if controller supports zone append
Zone append is an optional command in the Zoned Namespace Command Set.
Add a convenience function to check if the controller supports the zone
append command.

The ratified NVMe TP 4056 added a CSI field (in cdw14) to the Get Log Page
command. However, since there already exist two public functions to get a
log page (spdk_nvme_ctrlr_cmd_get_log_page() and
spdk_nvme_ctrlr_cmd_get_log_page_ext()), avoid creating a third one for
now, since nvme_ctrlr_get_zns_cmd_and_effects_log() itself can leverage
one of the existing public functions.

5c5a44f008 test: Use PRId64 for portability
POSIX defines PRId64/PRIu64/PRIx64 for printing 64-bit values in a
portable way. Replace a few references to %ld to remove the assumption
about the size of a long. Similarly, use %z with size_t arguments.

Where the value being printed is an unsigned 64-bit value, use PRIu64
instead of %ld.

Add a cast when comparing an enum to an integer value.

Add an explicit uint64_t cast to the definition of BLOCK_CNT to prevent
value truncation.

3b461269d2 test/unit/lib/nvmf: Add unit test stubs
With some build environments (e.g. clang, see #1613) linking fails with
unresolved references. This is caused by the inclusion of 'unused code'
which is usually discarded by the linker. The 'unused code' contains
references to functions that have not been 'stubbed' out. The failure
can be seen by removing 'LDFLAGS += -Wl,--gc-sections' in
spdk.unittest.mk

Resolved by adding stubs for missing references. These are never called
so return an arbtrary default value.

Fixes #1613

fce9428772 nvmf: Async event support for discovery log change
Added asynchronous event notices for discovery log change
as per nvme fabrics spec 1.1. This allows a host with persistent
connection to discovery controller to automatically connect to any
new subsystem available to the host automatically.

According to nvme fabrics spec 1.1, if the connect command specifies a
non-zero keep alive timer value and the discovery controller does not
support asynchronous events then we need to return Connect Invalid.
Since SPDK does not implement this check instead added support
for asynchronous events in discovery controller.

of ICD for admin and fabric commands. Transport configuration
parameter in_capsule_data_size is applied to all qpair types -
admin and IO. Also we allocate resources when we get a connection
request, so we don't know qpair type at this moment.
Create a list of buffer in TCP poll group to support ICD up
to 8192 bytes when configuration ICD is less than this value.
The number of elements in this pool is hardcoded, it is planned
to add a new configuration parameter later.

e385cafa72 nvme: Don't log an error when we can't resubmit all requests
In TCP NVME initiator with zero copy enabled requests might be
completed asynchronously - out of qpair_process_completions
context. At the same time we calculate requests completed
asynchronously so that generic NVME layer can resubmit
queued requests after calling qpair_process_requests (or
poll_group_process_requests).
But there is a time gap between async request complete and
qpair_process_completions and the user can submit new IO
thereby decrease the number of free TCP requests. That means
that there might be less free requests than we excpected when
we try to resubmit queued requests.
The solution is change ERRLOG to DEBUG log since it is not a
fatal case.

user descriptors to a pre-allocated ring per pre-allocated batch.

In addition, the other major change here is in how we poll for
completions.  We used to poll the batch rings then the main ring.
Now when commands are prepared their completion address is added to
a per channel list and the poller simply runs through that list
not caring which ring the completion address belongs too. This
simplifies the completion logic considerably and will avoid
polling locations that can't potentially have a completion.

Some minor rework was included as well, mainly getting rid of the
ring_ctrl struct as it didn't serve much of a purpose anyway and
with how things are setup now its easier to read with all the
elements in the channel struct.

Also, a change that came in while this was WIP needed a few fixes
to function correctly.  Addressed those and moved them to a
helper function so we have one point of control for xlations.

Added support for NOP in cases where a batch is submitted with
only 1 descriptor.

78ad672861 lib/event: remove legacy configuration from event framework
All options -c, --config and --json are valid, but have to
point to JSON configuration file.

Adjusted UT since JSON configs don't work with --wait-for-rpc.

Since this removes last reference to legacy INI configuration,
updated conf library to no longer mention the deprecation.
All uses of conf library are for explicit reason and not
related to SPDK event framework configuration.

Use callback function to remove controller from the attached list after

As for the vhost-nvme target, since we are developing

it now.

To complement that, transports will now also have their own
