cf4ab8a6de nvme: add DELAY_BEFORE_INIT quirk to Intel 0x0A54 SSD
This quirk was already applied to the 0x0A53 SSD, but is
likely needed on 0x0A54 as well.

Possible fix for issue #2231.

46b355c0ef nvme: add an API to check existing transport type is fabric or not
We already provides the API `spdk_nvme_ctrlr_is_fabrics` to return
input controller is fabrics controller or not, but it needs a controller
data structure as the input, so here we add another API to do the same
thing and it takes the transport type as the input, with this change,
both nvme and nvmf library can use the API.

Also we should treat UINT8_MAX(255) as valid fabrics transport type.

e40bd53175 nvme/pcie: only set qpair state from qpair's thread
The qpair's state member is only 3 bits of a uint8_t,
and the in_completion_context bit is another bit in that
same uint8_t.

We know that the qpair's state is only ever updated by
one thread, but it is possible that the state could
be modified by one thread, while another thread
is modifying in_completion_context.

in_completion_context is only modified by the thread
that is polling the qpair (or the qpair's poll group).
But with async mode, another thread that has a qpair
on the same PCIe controller could poll its adminq and
reap the SQ completion for the qpair that's owned by
the other thread.

So do *not* set the generic qpair state to CONNECTED
from the SQ completion callback.  Instead just set
the pcie_state to READY, and let the thread that owns
the qpair detect the qpair is READY and set the state
to CONNECTED itself.

Fixes issue #2157.

2696886c75 dma: Update translation result to hold iovec pointer
In some cases a single virtually contriguos memory
buffer can be translated to several chunks of memory.
To make such translation possible, update structure
spdk_memory_domain_translation_result to use a pointer
to iovec.
Add a single iov structure or cases where translation
is always 1:1, it will make easier translation callback
implementation. For RDMA transport translation of address
is always 1:1, so treat iovcnt other than 1 as an
error.

this context can be cast to a specific struct,

34c901e308 nvme/tcp: Fix tcp_req->datao calculation issue.
When data digest is enabled for a nvme tcp qpair, we can use accel_fw
to calculate the data crc32c. Then if there are multiple
c2h pdus are coming, we can use both CPU resource directly
and accel_fw framework to caculate the checksum. Then the datao value compare
will not match since we will not update "datao" in the pdu coming order.

For example, if we receive 4 pdus, named as A, B, C, D.
   offset   data_len (in bytes)
A:  0       8192
B:  8192    4096
C:  12288   8192
D:  20480   4096

For receving the pdu, we hope that we can continue exeution even if
we use the offloading engine in accel_fw. Then in this situation,
if Pdu(C) is offloaded by accel_fw. Then our logic will continue receving
PDU(D). And according to the logic in our code, this time we leverage CPU
to calculate crc32c (Because we only have one active pdu to receive data).
Then we find the expected data offset is still 12288. Because "datao" in tcp_req will
only be updated after calling nvme_tcp_c2h_data_payload_handle function. So
while we enter nvme_tcp_c2h_data_hdr_handle function, we will find the
expected datao value is not as expected compared with the data offset value
contained in Pdu(D).

So the solution is that we create a new variable "expected_datao"
in tcp_req to do the comparation because we want to comply with the tp8000 spec
and do the offset check.

We still need use "datao" to count whether we receive the whole data or not.
So we cannot reuse "datao" variable in an early way. Otherwise, we will
release tcp_req structure early and cause another bug.

PS: This bug was not found early because previously the sw path in accel_fw
directly calculated the crc32c and called the user callback. Now we use a list and the
poller to handle,  then it triggers this issue. Definitely, it will be much easier to
trigger this issue if we use real hardware engine.

Fixes #2098

Abort any queued admin requests once admin queue gets enabled. A request
can get queued if a controller is being reset and it gets submitted
while admin qpair is being reconnected.  If these requests aren't
aborted, the init process will stall, as requests don't get resubmitted
while controller is resetting and subsequent admin commands required for
the initialization would be queued too.

ccc084f3f3 nvme: check CC.EN bit asynchronously
Checking if the controller is enabled (CC.EN == 1) is now done without
blocking.

Additionally, a copy of the controller configuration register (CC) value
is now stored in spdk_nvme_ctrlr.process_init_cc.  It'll be updated in
subsequent patches whenever the register is written / read.  This will
make it possible to make several function non-blocking without having
send asynchronous register reads.

ca5ce67f6e nvme/rdma: Ignore completion when we can't find qpair
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.

3cb9bc2593 nvme: add spdk_nvme_ctrlr_prepare_for_reset()
This new API signals that the ctrlr will soon be
reset. This allows the transport to skip unnecessary
steps in following calls to the driver prior to the
reset - for example, skipping PCIe DELETE_SQ/CQ
commands when freeing an IO qpair.

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).
