Description
When UDP socket is being used to listen the multicast and if the network interface is disabled and then reenabled, the socket stops receiving packets.
Most likely reason of this is for Ipv4 multicast joins the first interface which not necessarily the first ipv4 but could be ipv6 in some cases and that leads to silent failure.
Attached example can be used to reproduce it.
