a6dbe3721e update Intel copyright notices
per Intel policy to include file commit date using git cmd
below.  The policy does not apply to non-Intel (C) notices.

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the 4 digit year from the result.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc).  Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line.  Simply there for
consistency.

488570ebd4 Replace most BSD 3-clause license text with SPDX identifier.
Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file.  This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.

Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text.  There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".

Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

9bff828f99 sock: introduce dynamic zerocopy according to data size
MSG_ZEROCOPY is not always effective as mentioned in
https://www.kernel.org/doc/html/v4.15/networking/msg_zerocopy.html.

Currently in spdk, once we enable sendmsg zerocopy, then all data
transferred through _sock_flush are sent with zerocopy, and vice
versa. Here dynamic zerocopy is introduced to allow data sent with
MSG_ZEROCOPY or not according to its size, which can be enabled by
setting "enable_dynamic_zerocopy" as true.

Test with 16 P4610 NVMe SSD, 2 initiators, target's and initiators'
configurations are the same as spdk report:
https://ci.spdk.io/download/performance-reports/SPDK_tcp_perf_report_2104.pdf

For posix socket, rw_percent=0(randwrite), it has 1.9%~8.3% performance boost
tested with target 1~40 cpu cores and qdepth=128,256,512. And it has no obvious
influence when read percentage is greater than 50%.

For uring socket, rw_percent=0(randwrite), it has 1.8%~7.9% performance boost
tested with target 1~40 cpu cores and qdepth=128,256,512. And it still has
1%~7% improvement when read percentage is greater than 50%.

6301f8915d lib/sock: provide a hint to picking optimal poll group
The process of matching qpair to poll group is split into
two distinct parts that occur on different threads.
See spdk_nvmf_tgt_new_qpair().

This results in a race condition for TCP between spdk_sock_map_lookup()
and spdk_sock_map_insert(), which are called in spdk_nvmf_get_optimal_poll_group()
and spdk_nvmf_poll_group_add() respectively.

Fixes #2113

This patch picks a hint from nvmf_tcp for next poll group,
which is then passed down to spdk_sock_map_lookup().

When matching placement_id exists, but does not have
a poll group assigned - the hint will be used.

59e44bcbb3 Revert "sock/uring: use batched manner to get the cqes."
This reverts commit 79215d80c1.

Reason: Find the bugs while using batched. For example, if
we fetch 3 CQEs, A, B, C and put it in a cqes[] array.
Then we leverage io uring cqe seen to handle, Then we handle the
CQE A, then invokes the call back related with A. In A's call back,
it may also call the reap function (sock_uring_group_reap),
then the CQEs will be handled again. Thus the CQEs B and C can be already
handled. Then we will handle B or C again, then it triggers the error.

This patch is used to add the async network I/O support in
sock layer. If code is configured with I/O uring, --with-uring,
we can use io uring in Linux (version >=5.4-rc3).

PS: We also make VPP's default priority > uring, because
for the iSCSI or sock test linked with VPP. It tests VPP with
a given address (which is not a special VPP can only open address),
so using uring can also listen those address succefully. And if we make
uring with priority > VPP, actually, VPP will not tested in those cases.

Additionally, the current CI pool is not ready for test, we need
wait for the CI system ready. And I test on my local platform, it works.
