    libertas: fix multicast filtering on eth and msh interfaces · 75bf45a7
    David Woodhouse authored
    We weren't properly handling multicast on the mesh interface. Fix that,
    which involves setting up the hardware to use the union of dev->mc_list
    for both eth%d and msh%d devices.
    
    This means we can't do it directly from ->set_multicast_list() because
    we'd need to lock the other device to read its list, and we can't do
    that because it might deadlock. So punt the actual work to keventd.
    
    Also, invoke the same when taking an interface down; for some reason the
    core calls ->set_multicast_list while IFF_UP is still set in dev->flags
    when we're taking it down, so its addresses don't get removed then.
    
    We also convert MAC_MULTICAST_ADR to a direct command while we're at it,
    removing one more entry from the big switch statement in the deprecated
    lbs_prepare_and_send_command() function.
