4d58c1328a nvmf: Move QID error checks to common path
QIDs need to be validated for both I/O queues and admin
queues, so move the checking to a common path.

b95fc6fc64 nvmf: Return the correct error for out-of-range QID
This one is actually a bit tough to deduce in the specification.
The NVMe-oF spec says that QID errors detected in the RDMA
transport shall return an RDMA-specific error indicating
the problem. However, our code doesn't detect the error in
RDMA-specific code, and it isn't clear if the language is
a "must" or a "should".

The NVMe specification does clearly indicate what error
to return on invalid QID in response to a Create
I/O Queue Pair command. For now, return that while
we game plan whether we need to call into the RDMA
transport to correctly report this error.

These are trivial to abort: since we just hold on to aer_req until an

85a822292d nvmf: refactor abort handling
Combine request lookup and abort into a single operation. Keeping them
separate would result in duplicating a lot of logic for finding the
proper list from which to remove aborted requests.

This is still a no-op for now, but it paves the way for aborting
requests that are still queued in software.

cbbec6dd16 nvmf: make each io qpair recycled by its own thread
This patch selects part of commit:
adfa9f6dc7

In the previous patch, the failed reason is the logic
that admin qpair actively destroys the ioqpair when
the admin qpair is recevied early. For this part,
we need to investigate it later since for multiple core
usage in our current handling case, we possibly have
admin qpair firstly to enter the destruct phase even if
the initiator sends the I/O qpair deletion first. Thus,
the ioqpair deletion can be recycled twice.

And this patch is selecting the part of the logic:
only to make each ioqpair recycled by its own thread.

27d47b9a10 nvmf: make the qpair disconnnect in the right order.
Reason: Initiator sends the qpair deletion in wrong order.
The correct order should be all io qpairs deletion and then
the admin qpair deletion. However, nvme perf does not follow
this since we did not catch ctrlr + c. If we catch ctrlr + c,
we need to use the spdk app framework, or other methods. We should
support this in another patch.

Morever, to prevent the incorrect behavior causing the coredump
of target, we need also consider such case in our NVMe-oF target
design. And this patch, can solve this issue, it will defer the
admin qpair deletion when there are still active io qpairs.

5c2952ab9d nvmf: implement NS Identification Descriptor list
Currently, this just reports the EUI64 and NGUID types, which are
already available in the Identify Namespace data, but this sets up the
framework for reporting a Namespace UUID (which doesn't have a
corresponding field in Identify Namespace) in the future.

30ef8cac7d nvmf: Solve the coredump issue when client conduct nvme disconnect
This patch is used to solve
https://github.com/spdk/spdk/issues/235

With multiple core bining for NVMe-oF target,
the qpairs which belonging to the same ctrlr may
be scheduled to different cores. Thus there is
resource contention to access the struct spdk_nvmf_ctrlr.

And we put the thread info in polling group. Morever,
we introduce an admin_qpair in ctrlr. Since admin_qpair will
always be created at first and freed at last, to reference
this pointer is safe.

Add a helper function, spdk_nvmf_qpair_is_admin_queue(), to make the
logic more obvious (akin to nvme_qpair_is_admin_queue() in the NVMe
library).
