The interface was wrongly hardwired to receive only multicast messages sent from the listener address, instead of accepting packets from everyone on the listener interface.
The actual restriction to listen only on the specific interface for multicast messages is a few lines further down.
Tested with a setup of crazyswarm on ROS-O, where Motive streams on a subnet and the linux-machine has separate interfaces for online access and Motive tracking.
