[PATCH] unit: Test netlink multicast group registration
by Ossama Othman
Register for the rtnetlink RTNLGRP_LINK multicast group to test the
ELL netlink multicast group registration code. Only registration and
deregistration is performed for now. An actual RTNLGRP_LINK multicast
notification is not triggered.
