SPDK can submit more commands to remote NVMf target than allowed by
negotiated queue size. SPDK submits up to SQSIZE commands, but only
SQSIZE-1 are allowed.
Here is a relevant quote from NVMe over Fabrics rev.1.1a ch.2.4.1
“Submission Queue Flow Control Negotiation”:
If SQ flow control is disabled, then the host should limit the number
of outstanding commands for a queue pair to be less than the size of
the Submission Queue. If the controller detects that the number of
outstanding commands for a queue pair is greater than or equal to the
size of the Submission Queue, then the controller shall:
a) stop processing commands and set the Controller Fatal
Status (CSTS.CFS) bit to ‘1’ (refer to section 10.5 in the NVMe Base
specification); and
b) terminate the NVMe Transport connection and end the association
between the host and the controller.

Each time the following file
"/sys/kernel/config/nvmet/subsystems/nqn_name/namespaces/ns_id/enable"
on the target side was changed, the SPDK initiator should receive an
async event (type: SPDK_NVME_ASYNC_EVENT_TYPE_NOTICE, info:
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
event received, just as the kernel initiator does.
Fixes#1825.

Aspects of bit fields are 'implementation defined'. On some platforms
alignment will occur if two adjacent fields are of different types. This
occurs in spdk_nvme_feat_async_event_configutation after the crit_warn
member which is effectively an int8_t, followed by an int16_t. There
isn't a generic way of changing the compiler's behaviour, so the best
options are:
- Change crit_warn to a uint32_t bit field and copy the value to/from
a spdk_nvme_critical_warning_state variable to use it. This requires
changes to code using the field.
- Adjust the structure definition to use smaller types to avoid the
problem. This preserves existing semantics, but the field order will
need to be reviewed if big-endian support is ever added (other places
in nvme_spec.h will need similar attention). A second reserved field
is required.
Use smaller types which seems the most straightforward option. Adjust
the use of the spdk_nvme_feat_async_event_configuration reserved fields
in lib/nvmf/ctrlr.c.
The new structure is binary compatible and the fields behave in the same
way, with the exception of an additional reserved field, so updating
CHANGELOG.md probably isn't necessary.

This commit provides the capability to install a
custom admin command handler for NVMF.
It can be used to implement or replace NVMe admin commands that
are currently not handled by the NVMF subsystem.
The handler implementation is pretty generic and the handler function
has to figure out what to do with the command based on the bdevs
that are configured for the subsystem.
In cases where admin commands need to be forwarded to an NVMe bdev,
the commit provides functions that allow access to the underlying bdev.
There is an example handler in lib/nvmf/custom_cmd_hdlr.c.
