04f9fac660 config/x86: skip GNU binutils bug check for LLVM
AVX512 was disabled when GNU binutils were missing or had a known bug,
even if LLVM binutils were used for the build,
because binutils-avx512-check.sh was invoked regardless and failed.
In particular, this was the case for FreeBSD with clang (default).
Run the check only when GNU binutils are used.

Fixes: 68b1f1cda5b4 ("build: check AVX512 rather than binutils version")

74822233bd test: create a list of extra tests
We removed some tests from the "CI" (fast-tests) list because they
were not reliable enough or did not make sense as non regression tests.
Since we still build those tests code, leave an option for users to call
them.
This list can also serve as a point where to document why test X is not

69f9d8aa35 examples/multi_process: fix Rx packets distribution
MP servers distributes Rx packets between clients according to
round-robin scheme.

Current implementation always started packets distribution from
the first client. That procedure resulted in uniform distribution
in cases when Rx packets number was around clients number
multiplication. However, if RX burst repeatedly returned single
packet, round-robin scheme would not work because all packets
were assigned to the first client only.

The patch does not restart packets distribution from
the first client.
Packets distribution always continues to the next client.

741b499e64 eventdev/eth_tx: fix queue delete logic
This patch fixes heap-use-after-free reported by ASan.

The application can use the queue_id as `-1` to delete all
the queues of the eth_device that are added to tx_adapter
instance.
In above case, the queue_del API is trying to use number of
queues from adapter level instead of eth_device queues.
When there are queues added from multiple eth devices,
it will result in heap-use-after-free as reported by ASAN.

This patch fixes the queue_del API to use correct number of
queues.

eab2ae4bc4 examples/l3fwd: use reserved addresses for EM mode
The l3fwd example should use the reserved IPv4/v6 reserved address
ranges defined in RFC5735, RFC5180 and RFC863 discard protocol for
the port number in the exact match mode of L3 forwarding.

fc89b4c8dd examples/l3fwd: print device name when adding routes
Since the number of Ethernet ports have gone up, print the device name
(which for PCI devices is the BDF triplet), along with the routes.
This is also helpful for cases where allow listing order is not honored.

cb94a679b7 examples/l3fwd: increase number of routes
Increase the number of routes from 8 to 16 that are statically added for
lpm and em mode as most of the SoCs support more than 8 interfaces.
The number of routes added is equal to the number of ethernet devices
ports enabled through port mask.

01fa83c94d net/af_xdp: workaround custom program loading
Since v0.4.0, if the underlying kernel supports it, libbpf uses 'bpf
link' to manage the programs on the interfaces of the XDP sockets (xsks).
This is not compatible with the PMD's custom XDP program loading feature
which uses the netlink-based method for loading custom programs.

The conflict arises when libbpf searches for a custom program on the
interface using bpf link, but doesn't find one because the netlink
method was used. libbpf then proceeds to try to load the default program
on the interface, but fails due to the presence of the custom program.

To work around this, the PMD now uses the
XSK_LIBBPF_FLAGS__INHIBIT_PROG_LOAD flag which prevents libbpf from
attempting to search for or load a program. One repercussion is that
DPDK must now insert the xsk into the xsks_map as this was previously
handled by libbpf during the routines for program loading/probing.

Ideally, the PMD would use bpf link to load the custom program, however
at present there is no convenient and reliable way of detecting whether
the underlying kernel supports bpf link. Perhaps this may become
available in a future libbpf release, at which point we can switch the
PMD over to the new bpf link based method.
