According to NVMe over Fabrics spec number of SGLs supported by the
controller is reported in MSDBD. But it is also implicitly limited by
command capsule size (IOCCSZ) since SGL are passed in capsule.
This patch adjusts max_sges to capsule size if required. Adjustment to
MSDBD is also moved to transport layer because it is fabrics specific
parameter and is not valid for PCIe transport.

SPDK can submit more commands to remote NVMf target than allowed by
negotiated queue size. SPDK submits up to SQSIZE commands, but only
SQSIZE-1 are allowed.
Here is a relevant quote from NVMe over Fabrics rev.1.1a ch.2.4.1
“Submission Queue Flow Control Negotiation”:
If SQ flow control is disabled, then the host should limit the number
of outstanding commands for a queue pair to be less than the size of
the Submission Queue. If the controller detects that the number of
outstanding commands for a queue pair is greater than or equal to the
size of the Submission Queue, then the controller shall:
a) stop processing commands and set the Controller Fatal
Status (CSTS.CFS) bit to ‘1’ (refer to section 10.5 in the NVMe Base
specification); and
b) terminate the NVMe Transport connection and end the association
between the host and the controller.

According to NVMe over Fabrics specification (rev.1.1a) HSQSIZE sent
in RDMA_CM_REQUEST private data (ch.7.3.6.4) shall be the same as
SQSIZE later sent in Connect command (ch.3.3).
SPDK NVMe RDMA initiator adjusts SQSIZE to CRQSIZE received from
target in RDMA_CM_ACCEPT private data. Target is allowed to send
CRQSIZE < HSQSIZE if RNR retries are used. So, it is possible that
SQSIZE sent by SPDK will be lower than previously sent HSQSIZE. There
are targets validating this match and they reject connection from
SPDK.
Linux kernel NVMe initiator doesn't perform such adjustments and
connects well to such targets.
This patch aligns SPDK behavior with specification and Linux kernel
implementation.

In current implementation RDMA qpair is destroyed right after
disconnect. That is not graceful qpair shutdown process since
there can be requests submitted to HW and we may receive
completions for already destroyed/freed qpair.
To avoid this, only disconnect qpair in ctrlr_disconnect_qpair
transport callback, all other resources will be released in
ctrlr_delete_io_qpair cb.
This patch is useful when nvme poll groups are used since in
that case we use shared CQ, if the disconnected qpair has WRs
submitted to HW then qpair's destruction will be deferred to
poll group.
When nvme poll groups are not used, this patch doesn't change
anything, in that case destruction flow is still ungraceful.
However since CQ is destroyed immediately after qpair,
we shouldn't receive any requests which point to released
resources. A correct solution for non-poll group case
requires async diconnect API which may lead to significant
rework.
There is a bug when Soft Roce is used - we may receive
a completion with "normal" status when qpair is already
disconnected and all nvme requests are aborted. Added
a workaround for it.

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

wrap all check in macro. Add unit test to verify this fix.
