70f9ae1f9b nvme: rename nvme_qpair_abort_reqs to *_with_cbarg
Renamed nvme_qpair_abort_reqs() to nvme_qpair_abort_reqs_with_cbarg() to
highlight the fact that it only aborts requests with specified cb_arg
and to distinguish it from _nvme_qpair_abort_reqs() which aborts all
requests immediately.

b0de620cfc nvme: disable keep-alive during controller reset
When a controller is reset, it goes through the whole init process,
including establishing keep-alive, so there's no point in sending it
during that time.  Additionally, it can stall the initialization if it
gets queued when adminq is connecting.

This patch introduces asynchronous versions of the ctrlr_(get|set)_reg

doesn't make sense (e.g. PCIe), the transport layer will call the
synchronous API and queue the callback to be executed during the next
process_completions call.

When poll_group is used, several qpairs share the same CQ
and it is possible to receive a completion with error (e.g.
IBV_WC_WR_FLUSH_ERR) for already disconnected qpair
That happens due to qpair is destroyed while there are
submitted but not completed send/receive Work Requests

To avoid such situation, we should not detroy ibv
qpair until we reap completions for all submitted
send/receive work requests. That requires some
rework in rdma transport and will be implemented
later

00277bc5d5 nvme/rdma: Fix searching for qpair by qp_num
Poll group holds lists of qpairs in different states and
when we got rdma completion with error, we iterate these
lists to find a qpair which qp_num matches. qp_num
is stored inside of ibv_qp which belongs to spdk_rdma_qp
structure. When nvme_rdma_qpair is disconnected, pointer
to spdk_rdma_qp is cleaned but qpair may still exist in
poll group list and when we start searhing for qpair by
qp_num we may dereference NULL pointer.

This patch adds a check that pointer to spdk_rdma_qp
is valid before dereferencing it. To minimize boilerplate code,
wrap all check in macro. Add unit test to verify this fix.

971f07b9fb nvme: add tracing to pcie request path
John Kariuki tested this patch on a system with
several Intel P5800X Optane SSDs, to determine the
performance impact of adding these two
spdk_trace_records() in the main NVMe I/O path.

The pathological case (512B random reads on a single
Xeon core) decreased from 13.10M to 12.88M, or 1.7%.
Normal workloads (4KB+) would incur a smaller penalty
since the I/O rate would be much lower - maybe even
unnoticeable..

This is a really valuable tracepoint to have enabled
by default, so I think this small amount of degradation
is acceptable.

Note that if we are deleting a qpair after
prepare_for_reset was called, and the qpair is
still waiting for a CREATE_IO_CQ or CREATE_IO_SQ,
we cannot poll for those commands to complete,
but we also cannot free the qpair immediately.
So set a flag for this case to defer the
destruction until the outstanding CREATE_IO_CQ or
CREATE_IO_SQ callback is invoked (typically as an
aborted command when the reset happens).

15b7d3bacc nvme/pcie: defer bad vtophys to completion context
The pcie layer can't always detect bad addresses
in the request at submission time - for example,
the transport may not have any trackers available
and the request gets queued at the generic
nvme level.

So this means that we might detect vtophys failures
during submission time, or in a process_completions
context - the latter happening when we complete
one request which triggers submitting a new request.

Currently if the vtophys failure happens during
submission context, we return -EFAULT to the
caller *and* call the completion callback.  Nowhere
else in the driver do we do both - the intention
has always been that you get one or the other.

So make all of this consistent by tagging the
tracker and the qpair with a flag if we hit a vtophys
error in the submission path.  Return 0 to the caller,
who will then later get a completion callback for the
bad request when the qpair is next processed for
completions.

I considered a separate TAILQ to hold these 'bad'
trackers, but that would have required duplicating
quite a bit of the tracker completion code for this
one case.  The flag on the pqpair is already in the
hot cacheline, so it's cheap to check it.  We will
only interate the outstanding_tr list when that flag
is set, so this should have zero impact to performance.

Fixes issue #2085.
