0f91f952be replace Mellanox with NVIDIA
NVIDIA acquired Mellanox Technologies in 2020.
The DPDK documentation and code might still include instances
of or references to Mellanox trademarks (like BlueField and ConnectX)
that are now NVIDIA trademarks.

The PCI IDs and copyrights are unchanged.

a3ade5e34d doc: add shared guide for mlx5 drivers
Adds new documentation for MLX5 common driver that contains:
 - Its features list (doesn't exist for now).
 - Its devargs description.
 - Device configuration information and tutorial.
 - Quick Start Guide for Mellanox OFED/EN.

Move into this doc all shared information from other MLX5 PMD docs and
add them reference to new common doc.

350e25fabd compress/mlx5: add block size option
Currently, the compression block size is 15 by default, which
is the maximum.

Add "log-block-size" devarg to select compression block size manually.
The value provided should be between 4 to 15.
Any out-of-range value will be defaulted to 15.

8809f78c7d doc: fix driver names
Since the built driver filenames have changed in DPDK 20.11, we need to
update the driver doc to match.

Most drivers start their section with the driver filename highlighted in
bold, while a number were missing the highlight. When updating the names,
add the markers for bold text to any missing it, so as to have things more
consistent.

c13cecf60f compress/qat: support IM buffer too small operation
This patch implements a special way of buffer handling when internal
QAT IM buffer is too small for Huffman dynamic compression operation.
Instead of falling back to fixed compression, the operation is now
split into multiple smaller dynamic compression requests (possible to
execute on QAT) and their results are then combined and copied into
the output buffer. This is not possible if any checksum calculation
was requested - in such case the code falls back to fixed compression
as before.

026f21c0b9 common/qat: support dual threads for enqueue/dequeue
Remove the limitation whereby enqueue and dequeue must be
done in same thread.
The inflight calculation is reworked to be thread-safe for 2
threads - note this is not general multi-thread support, i.e
all enqueues to a qp must still be done in one thread and
all dequeues must be done in one thread, but enqueues and
dequeues may be in separate threads.
Documentation updated.

218c4e68c1 mk: use linux and freebsd in config names
Rather than using linuxapp and bsdapp everywhere, we can change things to
use the, more readable, terms "linux" and "freebsd" in our build configs.
Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e.  both
"make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc"
work.

a9de470cc7 test: move to app directory
Since all other apps have been moved to the "app" folder, the autotest app
remains alone in the test folder. Rather than having an entire top-level
folder for this, we can move it back to where it all started in early
versions of DPDK - the "app/" folder.

This move has a couple of advantages:
* This reduces clutter at the top level of the project, due to one less
  folder.
* It eliminates the separate build task necessary for building the
  autotests using make "make test-build" which means that developers are
  less likely to miss something in their own compilation tests
* It re-aligns the final location of the test binary in the app folder when
  building with make with it's location in the source tree.

For meson builds, the autotest app is different from the other apps in that
it needs a series of different test cases defined for it for use by "meson
test". Therefore, it does not get built as part of the main loop in the
app folder, but gets built separately at the end.

a6531d58b4 compressdev: replace mbuf scatter gather flag
The current mbuf scatter gather feature flag is
too ambiguous, as it is not clear if input and/or output
buffers can be scatter gather mbufs or not.

Therefore, three new flags will replace this flag:
- RTE_COMP_FF_OOP_SGL_IN_SGL_OUT
- RTE_COMP_FF_OOP_SGL_IN_FB_OUT
- RTE_COMP_FF_OOP_LB_IN_SGL_OUT

Note that out-of-place flat buffers is supported by default
and in-place is not supported by the library.
