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
