Hi Jeremy,

Thanks for the report. I'm including the upstream git commit id and summary for the kernel team to reference and cherrypick. Thanks.

    [NET]: Messed multicast lists after dev_mc_sync/unsync

    Commit a0a400d79e3dd7843e7e81baa3ef2957bdc292d0 ("[NET]: dev_mcast:
    add multicast list synchronization helpers") from you introduced a new
    field "da_synced" to struct dev_addr_list that is not properly
    initialized to 0. So when any of the current users (8021q, macvlan,
    mac80211) calls dev_mc_sync/unsync they mess the address list for both
    devices.

    The attached patch fixed it for me and avoid future problems.
