The patches seem to fail on kernel 5.4. This is running on Debian with
5.4.0-2 packaged kernel, and using Stefan's DKMS package:

Title:
Dell D6000 dock lacks multicast Ethernet functionality
Status in Linux:
Confirmed
Status in linux package in Ubuntu:
Triaged
Bug description:
Dell D6000 exposes a CDC_NCM device for Ethernet traffic. However,
multicast Ethernet traffic is not processed making IPv6 not
functional. Other services, like mDNS used for LAN service discovery
are also hindered.
The actual reason is that CDC_NCM driver was not processing requests
to filter (admit) multicast traffic. I provide two patches to the
linux kernel that admit all Ethernet multicast traffic whenever a
multicast group is being joined.
The solution is not optimal, as it makes the system receive more
traffic than that strictly needed, but otherwise this only happens
when the computer is connected to a dock and thus is running on AC
power. I believe it is not worth the hassle to join only the requested
groups. This is the same that is done in the CDN_ETHER driver.
