selftests: net: bridge: add initial MLDv2 include test
Add the initial setup for MLDv2 tests with the first test of a simple is_include report. For MLDv2 we need to setup the bridge properly and we also send the full precooked packets instead of relying on mausezahn to fill in some parts. For verification we use the generic S,G state checking functions from lib.sh. Signed-off-by: Nikolay Aleksandrov <nikolay@nvidia.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
