a3f8150eac net/ifcvf: add ifcvf vDPA driver
The IFCVF vDPA (vhost data path acceleration) driver provides support for
the Intel FPGA 100G VF (IFCVF). IFCVF's datapath is virtio ring compatible,
it works as a HW vhost backend which can send/receive packets to/from
virtio directly by DMA.

Different VF devices serve different virtio frontends which are in
different VMs, so each VF needs to have its own DMA address translation
service. During the driver probe a new container is created, with this
container vDPA driver can program DMA remapping table with the VM's memory
region information.

Key vDPA driver ops implemented:

- ifcvf_dev_config:
  Enable VF data path with virtio information provided by vhost lib,
  including IOMMU programming to enable VF DMA to VM's memory, VFIO
  interrupt setup to route HW interrupt to virtio driver, create notify
  relay thread to translate virtio driver's kick to a MMIO write onto HW,
  HW queues configuration.

- ifcvf_dev_close:
  Revoke all the setup in ifcvf_dev_config.

Live migration feature is supported by IFCVF and this driver enables
it. For the dirty page logging, VF helps to log for packet buffer write,
driver helps to make the used ring as dirty when device stops.

Because vDPA driver needs to set up MSI-X vector to interrupt the
guest, only vfio-pci is supported currently.

6ace79505d mk: fix make defconfig on FreeBSD
On FreeBSD, make defconfig generates the config as
"defconfig_x86_64-bsdapp-", which does not resolve to any known
config file.

On FreeBSD, we get amd64 out of "uname -m", which was not handled by
the list of checks, but which now resolves to x86_64-native.

Then we run '$CC --version', and use grep -o with the list of known
compilers, and set to either gcc, icc or clang. Grep's '-o' option
returns the matched word rather than the whole line, making the
result easier to use.

The remaining code in the patch then takes ${compiler}, the "uname -m"
output and assembles them all together into a valid freebsd config name,
i.e. "defconfig_x86_64-native-bsdapp-clang".

5364de644a eal: support strlcpy function
The strncpy function is error prone for doing "safe" string copies, so
we generally try to use "snprintf" instead in the code. The function
"strlcpy" is a better alternative, since it better conveys the
intention of the programmer, and doesn't suffer from the non-null
terminating behaviour of it's n'ed brethern.

The downside of this function is that it is not available by default
on linux, though standard in the BSD's. It is available on most
distros by installing "libbsd" package.

This patch therefore provides the following in rte_string_fns.h to ensure
that strlcpy is available there:
* for BSD, include string.h as normal
* if RTE_USE_LIBBSD is set, include <bsd/string.h>
* if not set, fallback to snprintf for strlcpy

Using make build system, the RTE_USE_LIBBSD is a hard-coded value to "n",
but when using meson, it's automatically set based on what is available
on the platform.

59b91bec12 net/mlx5: spawn rdma-core dependency plug-in
When mlx5 is not compiled directly as an independent shared object (e.g.
CONFIG_RTE_BUILD_SHARED_LIB not enabled for performance reasons), DPDK
applications inherit its dependencies on libibverbs and libmlx5 through
rte.app.mk.

This is an issue both when DPDK is delivered as a binary package (Linux
distributions) and for end users because rdma-core then propagates as a
mandatory dependency for everything.

Application writers relying on binary DPDK packages are not necessarily
aware of this fact and may end up delivering packages with broken
dependencies.

This patch therefore introduces an intermediate internal plug-in
hard-linked with rdma-core (to preserve symbol versioning) loaded by the
PMD through dlopen(), so that a missing rdma-core does not cause unresolved
symbols, allowing applications to start normally.

c88b3f2558 rawdev: introduce raw device library
Each device in DPDK has a type associated with it - ethernet, crypto,
event etc. This patch introduces 'rawdevice' which is a generic
type of device, not currently handled out-of-the-box by DPDK.

A device which can be scanned on an installed bus (pci, fslmc, ...)
or instantiated through devargs, can be interfaced using
standardized APIs just like other standardized devices.

This library introduces an API set which can be plugged on the
northbound side to the application layer, and on the southbound side
to the driver layer.

The APIs of rawdev library exposes some generic operations which can
enable configuration and I/O with the raw devices. Using opaque
data (pointer) as API arguments, library allows a high flexibility
for application and driver implementation.

This patch introduces basic device operations like start, stop, reset,
queue and info support.
Subsequent patches would introduce other operations like buffer
enqueue/dequeue and firmware support.

cbc12b0a96 mk: do not generate LDLIBS from directory dependencies
The list of libraries in LDLIBS was generated from the DEPDIRS-xyz
variable. This is valid when the subdirectory name match the library
name, but it's not always the case, especially for PMDs.

The patches removes this feature and explicitly adds the proper
libraries in LDLIBS.

Some DEPDIRS-xyz variables become useless, remove them.

84cc318424 eal/x86: select optimized memcpy at run-time
This patch dynamically selects functions of memcpy at run-time based
on CPU flags that current machine supports. This patch uses function
pointers which are bind to the relative functions at constrctor time.
In addition, AVX512 instructions set would be compiled only if users
config it enabled and the compiler supports it.

078b8b452e net/mlx4: add RSS flow rule action support
This patch dissociates single-queue indirection tables and hash QP objects
from Rx queue structures to relinquish their control to users through the
RSS flow rule action, while simultaneously allowing multiple queues to be
associated with RSS contexts.

Flow rules share identical RSS contexts (hashed fields, hash key, target
queues) to save on memory and other resources. The trade-off is some added
complexity due to reference counters management on RSS contexts.

The QUEUE action is re-implemented on top of an automatically-generated
single-queue RSS context.

The following hardware limitations apply to RSS contexts:

- The number of queues in a group must be a power of two.
- Queue indices must be consecutive, for instance the [0 1 2 3] set is
  allowed, however [3 2 1 0], [0 2 1 3] and [0 0 1 1 2 3 3 3] are not.
- The first queue of a group must be aligned to a multiple of the context
  size, e.g. if queues [0 1 2 3 4] are defined globally, allowed group
  combinations are [0 1] and [2 3]; groups [1 2] and [3 4] are not
  supported.
- RSS hash key, while configurable per context, must be exactly 40 bytes
  long.
- The only supported hash algorithm is Toeplitz.

1cd28daf82 mk: install symlinks before build step
A race condition can happen during parallel builds, where a header
might be installed in RTE_OUT/include before CFLAGS is recursively
expanded. This causes GCC to sometimes pick the header path as
SRCDIR/... and sometimes as RTE_OUT/include/... making the build
unreproducible, as the full path is used for the expansion of
__FILE__ and in the DWARF directory listing.

Installing all symlinks before all builds solves the problem. It is
still suboptimal, as the (fixed) path recorded in the DWARF dir
listing will include the user-configurable build output directory,
and thus will result in a different binary between different users
despite all other conditions being equal, but it is a simpler
approach that will anyway be obsolete once the build system is
switched to Meson.
