From: Nikolay Aleksandrov <nikolay@xxxxxxxxxx>
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.
