Socket request has iov vector of limited size and when
DIF insert of strip feature is enabled we send each data
block as separate iov element to remove metadata.
In the case of large read operation there might be not
enough iov elements to describe all data block. In this
case we can send several C2H PDUs.
To estimate the number of bytes that can be written
with single C2H we try to fill socket iovs. That is
not so cheap operation so this fix is implemented
for DIF case only. Also data buffers in regular
read operation should always fit into socket iov
vector.
Fixes issue #1674

Reason: After this patch, the last nvme command cannot be executed

If the user decided to disable ICD then we have several side effects:
1. SPDK prints several warnings/errors
2. SPDK doesn't create recv pipe and doesn't set SO_RCVBUF socket option.
I think that we should not rely on ICD only when we create recv pipe or
set SO_RCVBUF since data may be transferred in sgls via R2T/H2C and
we still need recv_pipe and SO_RCVBUF for better performance.
Alternative option is to set recv_buf_size as a maximum between
ICD and io_unit_size

nvmf_tcp_req_set_state(). Hence explicit dequeuing only when the
state of the request is NEED_BUFFERING.
Most abort operation is common between two cases. We can use fallthrough
in switch-case but factor out the common operation into a helper
function nvmf_tcp_req_set_abort_status() instead because we may use
the helper function in future and using helper function is easier to
read than fallthrough.

nvmf_tcp_qpair_abort_request() returns immediately if rc is

State machine is different among NVMe-oF transports and is
encapsulated to the transport neutral NVMe-oF controller and
NVMe-oF qpair.
To implement abort operation for each NVMe-oF transport,
add a function pointer qpair_abort_request to struct spdk_nvmf_transport_ops
and a stub nvmf_transport_qpair_abort_request() to encapsulate
which transport is used.
The following patches will implement qpair_abort_request for each
transport. Each qpair_abort_request() is responsible to call
spdk_nvmf_request_complete() for the abort request.

It should return "NVME_TCP_PDU_FATAL". I think that
this issue is introduced after we move the data
copy from tcp transport layer to the socket
layer. And it should return "NVME_TCP_PDU_FATAL now",
and it will be consistent with the logic in the same
function.
With this patch, it will fix the big I/O size write
from the initiator.

This parameter describes the number of admin and IO
qpairs while admin qpair always exists and should not
be configured explicitly.
Introduce a new parameter `max_io_qpairs_per_ctrlr`
which configures the number of IO qpairs.
Internal structure of NVMF transport is not changed,
both RPC parameters configure the same nvmf transport parameter.
Deprecate max_qpairs_per_ctrlr in spdkcli as well
Side change: update dif_insert_or_strip description -
it can be used by TCP and RDMA transports
Config files parsing is not changed since it is deprecated

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.

Purpose: To set the priority of the NVMe-oF connection especially
for TCP connection.
For example, the previous example can be:
trtype:TCP adrfam:IPv4 traddr:10.67.110.181 trsvcid:4420
With the change, it could be:
trtype:TCP adrfam:IPv4 traddr:10.67.110.181 trsvcid:4420 priority:2
The priority is optional. We try to change
spdk_nvme_transport_id but not in spdk_nvme_ctrlr_opts since
the opts in spdk_nvme_ctrlr_opts will reflect in every nvme ctrlr,
this is short of flexibility.

The code used to do this but it was removed when the buffering was
shifted down to the posix layer. Add a way for users of sockets
to still properly size the buffers.
This also means that by default, the receive buffering is not enabled
