In SPDK NVMe/TCP target, when initializing the socket, the low
watermark is set to sizeof(struct spdk_nvme_tcp_common_pdu_hdr),
which is 24 bytes. In our testing, some times there might be very
small data packet (as small as 16 bytes) be sent to wire. After
this, if there is no more data sent to the same socket, this small
data packet won’t be received by NVMe/TCP controller qpair thread
because the size hasn’t reached the low watermark. Because of this,
the qpair thread is waiting for more data come in and the initiator
is waiting for the IO request to be completed. Hence the delay
happens.
As the minimum data that allows target to determine the PDU type is
sizeof(struct spdk_nvme_tcp_common_pdu_hdr), which is 8 bytes, we
changed low watermark setting as below. With the change, the problem
was gone immediately.

Historically, we have immediately called the qpair
fini function directly from _spdk_nvmf_qpair_destroy.
However, to fix a race with initiators where we can get
a duplicate QID from the initiator, we will have to clear
the QID bit before calling qpair_fini. Clearing the QID bit
must be done on the controller thread, so we have to pass at
least two messages between calling _spdk_nvmf_qpair_destroy
and qpair_fini. This leaves a gap where we can poll the poll group
and reap completions for the qpair before we call qpair_fini and drain
all of the requests related with the qpair.

The next patch will create poll group threads dynamically for
NVMe-oF target, and will need to wait for completion of poll group and
I/O channel destroy. This is a preparation for the next patch.
Add callback function and its argument to spdk_nvmf_poll_group_destroy(),
and to struct spdk_nvmf_poll_group, respectively.
The callback has not only cb_arg but also status as its parameters even
if the next patch always sets the status to zero. The reason is to follow
spdk_nvmf_tgt_destroy's callback and to process any case that the status
is nonzero in future.
spdk_nvmf_poll_group_destroy() sets the passed callback to the passed
poll group.
Then spdk_nvmf_tgt_destroy_poll_group() calls the held callback in the
end.
This change will ensure all pollers are being unregistered and
all I/O channels are being released.

However, we're moving to add a new call to associated a listener with a

will actually be performed there. For simplicity, make this synchronous

When a command arrives and no requests are available, the socket
recv state machine sits in the RECV_STATE_AWAIT_REQ state until another
network event occurs. If this I/O was the last one sent, this leaves the
target hung. To fix this, when a request is completed, kick the state
machine to make forward progress.
In practice, this can only occur once the pdu send acknowledgements are
asynchronous relative to arriving commands. That only begins happening
with the use of MSG_ZEROCOPY. When MSG_ZEROCOPY is turned on, it's
possible receive the next PDU in a chain for a command prior to seeing
the acknowledgement that the response that triggered that PDU actually
sent.

Previously, the R2T was sent and if an H2C arrived prior
to seeing the R2T ack, it was processed anyway. Serialize
this process.
In practice, if the H2C arrives with a correctly functioning
initiator, that means the R2T already made it to the initiator.
But because the PDU hasn't been released yet, immediately processing the
PDU requires an extra PDU associated with the request. Basically, making
this change halves the worst-case number of PDUs required per
connection.
In the current sock layer implementations, it's not actually possible
for the R2T send ack to occur after that H2C arrives. But with the
upcoming addition of MSG_ZEROCOPY and other sock implementations, it's
best to fix this now.

With our target design, there's no advantage to sending
multiple R2T PDUs per nvme command. This patch starts by
setting up the math so that at most 1 R2T PDU is required
per request. This can be guaranteed because the maximum
data transfer size (MDTS) is pre-negotiated in NVMe-oF
to a reasonable size at start up.
It then proceeds to simplify all of the logic around mapping
requests to PDUs. It turns out that the mapping is now always
1:1. There are two additional cases where there is no request
object at all but a PDU is still needed - the connection response
and termination request. Put an extra PDU on the queue object
for that purpose.
This is a major simplification.

The resources allocated to a queue pair do not need to be directly
correlated to the queue size requested by the initiator in NVMe-oF, as
long as enough resources are present. The RDMA transport, for instance,
does complex pooling of the resources behind the scenes when using a
shared receive queue.
Simplify the resource allocation for a TCP qpair to just always allocate
the max allowed queue size right away. This is a configurable parameter,
so system administrators can adjust for their needs. The initiator may
then request a queue size less than or equal to that, which will only be
enforced by queue depth counting and not impact the actual number of
resources allocated on the target.
This change relies on the MaxC2HSize being equal to the Maximum Data
Transfer Size (MDTS) reported. That is the default configuration, but
MDTS is configurable. Changing the MDTS with this patch to a value
larger than 128k will cause the target to break. This is addressed in
the next patch in this series.

By releasing the just-completed PDU prior to calling the callback,
for flows that immediately submit another PDU inside the callback,
the just-released PDU can be immediately reused. This reduces the number
of PDUs required in the pool to continue forward progress to half of the
previous value, while also making it more CPU cache friendly.

For ACWU we always set value 1 because bdev holds
information specific for namespace only. This value
actually does not matter because we also set NACWU
which makes ACWU irrelevant. We set ACWU because
NVMe specs requires ACWU != 0 if fused commands
are supported.
