Let's prune the jobs list to limit the amount of time spent by the robot
in Travis.

Since meson enables automatically the relevant components, there is not
much gain in testing with extra_packages vs required_packages.

For a given arch/compiler/env combination, compilation is first tested
in all jobs that run tests or build the docs or run the ABI checks.
In the same context, for jobs that accumulates running tests, building
the docs etc..., those steps are independent and can be split to save
some cpu on Travis.

With this, we go down from 21 to 15 jobs.

All ICMP fragments will still hit the rules like ETH, ETH + IP, and

In addition, When the user creates a RSS flow the PMD splits the flows
according to the flow RSS layers as the HW requests for RSS TIR.
The internal priority for each flow is decided by the flow last layer.
L2, L3 and L4 (L2 low and L4 high).

The tunnel layer was wrongly decided to be L4 all the time, even when
the flow is configured with inner-RSS.

Hence, the first RSS split which takes the tunnel layer priority all the
time will be matched before the more specific splits.

Change the priority of tunnel layer to be L2 when inner-RSS is

As a result, libibverbs, libmlx4, libmlx5 are listed in Requires.private
section (allowing to be linked as shared libraries) and libnl is missing.

A fix is in progress for meson, but anyway we will have to live without
such a fix until a better version of meson is widely available:
https://github.com/mesonbuild/meson/pull/6393

In order to avoid meson suggesting shared libraries in the section
Requires.private of the .pc file, the dependency object is recreated
with declare_dependency():
- cflags are extracted the libibverbs.pc
- ldflags, from libibverbs.pc, are processed to force
static flavor of ibverbs libraries, thanks to this syntax:
-l:libfoo.a

Thomas Monjalon [Wed, 12 Feb 2020 22:07:05 +0000 (23:07 +0100)]
buildtools: get static mlx dependencies for meson

The shell script options-ibverbs-static.sh was used with make
in forcing static linkage of ibverbs libraries.

When choosing to link with a static dependency in meson,
the generated .pc file will not force such static linkage.
The solution will rely on using this script in meson.

If linking with libraries installed in a non-standard path,
an option -L is provided via EXTRA_LDFLAGS in case of using make.
With meson, tuning PKG_CONFIG_PATH for pkg-config should be enough.
When statically linking an application, the .pc file must save the
-L path so the application link will work without any extra option.
That's why --libs-only-l is replaced with --libs which includes -L.
Options which are neither -l or -L are filtered out because not needed
and can cause compilation issues with the legacy system using make.

The other change in this script is to drop the first occurrences of the
main library file (libiverbs.a). Only the last occurrence is kept.
It fixes some undefined references when linking a static application
using libdpdk.pc.

net/mlx: add static ibverbs linkage with meson

The libibverbs (and libmlx4/5) can be statically embedded
in the shared PMD library, or in the application with the static PMD.
It was supported with make build system in
commit 2c0dd7b69fb0 ("config: add static linkage of mlx dependency").

The same feature is enabled with meson when using pkg-config
(i.e. only if the call to dependency() is successful).
The fallback method for searching library with cc.find_library()
is not supported because the dependencies of the found library
would not be linked (no such info in .a file unlike .so).

The main difference, in meson build system, is the generated .pc file
giving arguments to link DPDK with the application.
Unfortunately the .pc file will not keep memory of the static linkage
option for libibverbs.
