I think I've hit the same bug (Debian testing 4.18.0-2-amd64, with an i-tec docking station: https://i-tec.cz/en/produkt/cadua4kdockpdl-2/, but same driver and problems: IPv6 RA and IPv4+IPv6 mdns not working).
I think this shows an overview of the patches you submitted: https://patchwork.kernel.org/project/linux- usb/list/?submitter=181339&state=%2A&archive=both It seems patchwork can't figure out a patch series for your patches, and I'm also lost which patches I'd have to apply if I wanted to try them. Also all patches are "archived" (no idea what that means, but by default the search only looks for non-archived patches). Thanks for your work so far anyway! At least I know now it isn't my fault it isn't working :) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1779173 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.
