Multicast Ethernet traffic is not being received
I am the owner of a Dell D6000 dock station which, as far as I know, is a DisplayLink device. Everything is working almost perfectly under Ubuntu 18.04, but I was not receiving IPv6 traffic on the dock's Ethernet port.
Upon closer inspection, I have discovered that Ethernet multicast traffic does not reach the computer, only broadcast and unicast traffic does. I have checked this with the wireshark tool. This was the ultimate reason why IPv6 was failing to obtain a valid address.
I have also checked that mDNS, that also depends on proper Ethernet multicast, is not working, as avahi-discover does no show any device, unless I plug the computer to another dock in the same network segment.
I am more than willing to provide any assistance to help to solve this issue.
Best regards,
