distribution
This test suite validates the functionality of the devlink-rate API for
traffic class (TC) bandwidth allocation. It ensures that bandwidth can
be distributed between different traffic classes as configured, and
verifies that explicit TC-to-queue mapping is required for the
allocation to be effective.
The first test (test_no_tc_mapping_bandwidth) is marked as expected
failure on mlx5, since the hardware automatically enforces traffic
class separation by dynamically moving queues to the correct TC
scheduler, even without explicit TC-to-queue mapping configuration.
Test output on mlx5:

Change netns of current thread and switch back on context exit.
For example:
with NetNSEnter("ns1"):
ip("link add dummy0 type dummy")
The command be executed in netns "ns1".

This change introduces a new selftest case to verify the functionality
of dumping IPv4 multicast addresses using the RTM_GETMULTICAST netlink
message. The test utilizes the ynl library to interact with the
netlink interface and validate that the kernel correctly reports the
joined IPv4 multicast addresses.
To run the test, execute the following command:
$ vng -v --user root --cpus 16 -- \
make -C tools/testing/selftests TARGETS=net \
TEST_PROGS=rtnetlink.py TEST_GEN_PROGS="" run_tests

Nothing surprising here, hopefully. Wrap the variables from
the environment into a class or spawn a netdevsim based env
and pass it to the tests.

Add drivers/net as a target for mixed-use tests.
The setup is expected to work similarly to the forwarding tests.
Since we only need one interface (unlike forwarding tests)
read the target device name from NETIF. If not present we'll
try to run the test against netdevsim.

Add glue code for accessing the YNL library which lives under
tools/net and YAML spec files from under Documentation/.
Automatically figure out if tests are run in tree or not.
Since we'll want to use this library both from net and
drivers/net test targets make the library a target as well,
and automatically include it when net or drivers/net are
included. Making net/lib a target ensures that we end up
with only one copy of it, and saves us some path guessing.
Add a tiny bit of formatting support to be able to output KTAP
from the start.
