RDMA QP is attempted to recover after IBV_EVENT_QP_FATAL event
is received from IBV asynchronous event API.
RDMA QP is put into ERROR state and is not processing any inbound
requests. The outstanding requests are only allowed to COMPLETED
and FREE states, no outbound transfers are performed.
IBV_EVENT_QP_LAST_WQE_REACHED or IBV_EVENT_SQ_DRAINED event is
expected to follow IBV_EVENT_QP_FATAL, giving a go to draining of
all outstanding requests and freeing the associated resources.
The requests executed by block layer are gracefully allowed to
complete, but no outbound transfers are made.
Note, outstanding requests can not be reliably completed through
polling the CQ, as WC's with failure status might not have all
the fields valid. The failed WC's are dropped and the outstanding
requests are fetched from the appropriate state's linked list.
QP recovery is triggered when there is no more outstanding requests.
If QP recovery is completed succesfully, the RDMA QP is put back into
ACTIVE state, the QP disconnect is triggered otherwise.

This was partially fixed in commit 1e481d0438 ("nvmf: Do not allow NN

where the user asked to add a NS with a NSID outside the current NN.
This patch reworks the logic (again) to be more straightforward and
hopefully more obviously correct.
Some confusion between max_allowed_nsid and max_nsid is also clarified;
if max_allowed_nsid is set, then max_nsid == max_allowed_nsid at all
times, so we don't need the extra logic when calculating NN in
spdk_nvmf_ctrlr_identify_ctrlr().

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.

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.

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.

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.

Instead of scattering direct calls to the function
callbacks throughout the code, add some wrappers.
This will make some later refactoring marginally
easier.

Create one transport per nvmf target. Today, there is just
one global nvmf target, but this paves the way for multiple.

Match the terminology used in the NVMe-oF specification,
which is queue pair. For the RDMA transport, this maps to
an RDMA queue pair, but may map to other things for other
transports. It still is logically a "connection" from
a networking sense.

This is just a rename - the functionality hasn't changed.
Use the same terminology as the specification (which is controller)
so those familiar with the specification can more easily
approach the code base.
This is still conceptually equivalent to a "session" in the
networking sense.
