1681a055f9 nvme/pcie: restore timeout checking on admin queue
This was partially fixed in commit ddeaeeec19 ("nvme: Only check
timeouts on requests from the same process"), but the function that
calls nvme_pcie_qpair_check_timeout() was also erroneously filtering out
the admin queue.  Restore the original behavior of checking all queue
types.

4c4c8ca269 nvme: don't reset controller when processing NS mangement commands
For attach/detach command, the identify namespace data should be
updated during the namespace attribute notice event callback, while
here, in case of the driver may not set aer callback, so update the
namespace identify same with attach command.

be1c82b7a8 nvme: update the NS identify data according to AER
Number of Namespaces of controller identify structure
defines the maximum number of namespaces supported by
this controller, for physical NVMe controllers, the NN
is a fixed number, while here, we set the same rule for
NVMeoF controllers.

After NVMe driver got namespace notice event, it should
update the namespace identify data structure for NS
attach/detach commands.

This will be used later instead of retrieving VS (potentially via a Get
property command for Fabrics) multiple times.

The Active NS List code was previously depending on the VER field of the
Identify Controller data, but this was only added with NVMe 1.2, so we
can't rely on it to detect NVMe 1.1 controllers; it is changed to use
the new cache VS value instead.

ffee381d82 nvme: allow a minimum of 10 seconds for shutdown
Some devices may report a RTD3E time that is shorter than their actual
shutdown time in practice; force the timeout to be at least 10 seconds
to allow for a reasonable amount of shutdown time.

This doesn't add any extra delay for devices that do complete the
shutdown process within their reported RTD3E time, since we will return
as soon as the device reports that it is finished shutting down.

When a ctrlr is failed to initialize and to respond other
requests, the nvme_ctrlr_fail() will be always called. Add
a log there to have the traddr information so that applications

acb9d2488d nvme: use RTD3E to determine shutdown timeout
NVMe 1.2 introduced a new Identify Controller field, RTD3E ("RTD3 Entry
Latency"), which allows the device to report the expected time for a
normal shutdown.  Use this as the timeout for the shutdown process when
available instead of hard-coding 5 seconds.

6368d6c0f5 nvme: add new spdk_nvme_connect() API to directly attach the ctrlr
With this new API, callers can attach one specific ctrlr identified by
the transport ID directly along with optional ctrlr opts. If connecting
to multiple controllers, it is still suggested to use spdk_nvme_probe()
and filter the requested controllers with the probe callback.

Two primary use cases:
1) connecting to the NVMe-oF discovery controller
2) more straightforward way to connect a specific controller (avoiding
the probe callback)

A typical usage of this API with specific ctrlr_opts:
1. struct spdk_nvme_ctrlr_opts user_opts = {}
2. Call spdk_nvme_ctrlr_get_default_ctrlr_opts(&user_opts, sizeof(user_opts))
3. Modify the content of the initialized user_opts with user required value like
   user_opts.num_io_queues = 8
4. Call spdk_nvme_connect(&trid, &user_opts, sizeof(user_opts))

dc2fb2ed39 nvme: add a public API to rename spdk_nvme_ctrlr_opts_set_defaults

include/spdk/nvme.h. This new spdk_nvme_connect() API will connect the user
specified trid and have a user optional ctlr opts. Rename this API and make
it as public.

A typical usage of this API as following:

2. Call spdk_nvme_ctrlr_get_default_ctrlr_opts(&user_opts, sizeof(user_opts))

This patch cleans up the uses of PAGE_SIZE in the NVMe driver; the
behavior is still the same in all cases today, since normal NVMe
controllers report a minimum page size of 4096.
