a339694621 raw/ioat: fix work-queue config size
According to latest DSA spec[1], the work-queue config register size
should be based off a value read from the WQ capabilities register.
Update driver to read this value and base the start of each WQ config
off that value.

30105f664f drivers: add headers install helper

Note: this change fixes an issue with the crypto scheduler headers which

a20b2c01a7 build: standardize component names and defines
As discussed on the dpdk-dev mailing list[1], we can make some easy
improvements in standardizing the naming of the various components in DPDK,
and their associated feature-enabled macros.

Following this patch, each library will have the name in format,
'librte_<name>.so', and the macro indicating that library is enabled in the
build will have the form 'RTE_LIB_<NAME>'.

Similarly, for libraries, the equivalent name formats and macros are:
'librte_<class>_<name>.so' and 'RTE_<CLASS>_<NAME>', where class is the
device type taken from the relevant driver subdirectory name, i.e. 'net',
'crypto' etc.

To avoid too many changes at once for end applications, the old macro names
will still be provided in the build in this release, but will be removed
subsequently.

There is a null pointer check in 'idxd_vdev_parse_params()' which is

e640362b34 raw/skeleton: allow closing already closed device
This patch return OK code (0) from skeleton_rawdev_close function
if firmware is in SKELETON_FW_READY state. Formerly it returned
-EINVAL error code.

Returning an error here is troublesome as it disallows proper release
of the rawdev. The rte_rawdev_pmd_release function from librte_rawdev
library calls drivers' rawdev_close handler and continues execution
only in case of errorless call.
(see lib/librte_rawdev/rte_rawdev.c:540)

The SKELETON_FW_READY state is reached after creation, reset, unload
or close of the device. The device should be ok to be released in
such situations.

To reproduce issue fixed by this patch, call rawdev_autotest
from dpdk-test app for few times. As the device is not properly
released, the next calls will fail.

e356aa46ad avoid libfdt checks adding full paths to pkg-config
The checks for libfdt try dependency() first which would only work if
a pkg-config would be present but libfdt has none.
Then it probes for the lib path itself via cc.find_library.

But later it adds the result of either probe to ext_deps which ends up
in build and also the resulting pkg-config to contain toolchain versioned
paths in Libs.private like:
  /usr/lib/gcc/x86_64-linux-gnu/9/../../../x86_64-linux-gnu/libfdt.so
which obviously breaks on toolchain updates.

In general libs used multiple times - ipn3ke + ifpga in this case - are
checked centrally in config/meson.build so move it there and fix the
adding of dependencies to not use the full file path.

The result is libfdt in pkg-config now showing up as:
  Libs.private: -pthread -lm -ldl -lnuma -lfdt -lpcap

13f8e4a27e rawdev: allow queue config query to return error
The driver APIs for returning the queue default config can fail if the
parameters are invalid, or other reasons, so allow them to return error
codes to the rawdev layer and from hence to the app.

f574ed8116 rawdev: add private data size to queue config inputs
The queue setup and queue defaults query functions take a void * parameter
as configuration data, preventing any compile-time checking of the
parameters and limiting runtime checks. Adding in the length of the
expected structure provides a measure of typechecking, and can also be used
for ABI compatibility in future, since ABI changes involving structs almost
always involve a change in size.

8db9dce72d rawdev: add private data size to config inputs
Currently with the rawdev API there is no way to check that the structure
passed in via the dev_private pointer in the structure passed to configure
API is of the correct type - it's just checked that it is non-NULL. Adding
in the length of the expected structure provides a measure of typechecking,
and can also be used for ABI compatibility in future, since ABI changes
involving structs almost always involve a change in size.
