fdec444aa8 nvmf/rdma: track requests in any state
Requests that are being put into IBV context are lost when
IBV QP breaks and its SQ drains.

In order to track NVMf/RDMA requests, RDMA QP has been
reworked to track requests at any state with queues of
requests for each state.

This allowed to get rid of a few intermediate queues and
request counters.

A couple of states has been added to track outbound requests
with and without data. They will be used by QP recovery for
freeing resources assigned to outstanding requests.

5518a327a8 nvmf/rdma: fix error paths in spdk_nvmf_rdma_create
Most of the error paths in this function leaked resources.  Make them
all use spdk_nvmf_rdma_destroy() so all resources are consistently
freed.

The spdk_io_device_register() call is moved to the top of the function
so that the io_device is always valid when calling the destroy function.

eb387189c2 nvmf: don't change NN while ctrlrs exist
This was partially fixed in commit 1e481d0438e6 ("nvmf: Do not allow NN
to change while connections present"), but we did not handle the case
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().

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.

NVMf cnx acceptor poller is changed to check the asynchronous events
from the RDMA devices.

RDMA async events are polled together with RDMA CM events; the file
descriptors are combined into a poll fd array and processed in a single
poll syscall.

The errors handler is an empty placeholder for this patch, it just
prints the kind of event read from the IB device context.
The work for implementing event handling is left for later.

40b6f761b2 nvmf: allow abort of AER requests
These are trivial to abort: since we just hold on to aer_req until an
event is triggered, we just need to set aer_req back to NULL and
complete the request.

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.

Per the NVMe specification, NN cannot change while there
are connections present. There was originally a check
for this that was removed in commit 763ab88 to match
the behavior in the Linux kernel. However, after a
discussion with the NVMe specification committee, SPDK
was originally correct.

cbbec6dd16 nvmf: make each io qpair recycled by its own thread
This patch selects part of commit:
adfa9f6dc75d4c541beeb3269442552f7cbf5d7a

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.
