   3 Subject: batman-adv: Fix netlink dumping of all mcast_flags buckets
   4
   5 The bucket variable is only updated outside the loop over the mcast_flags
   6 buckets. It will only be updated during a dumping run when the dumping has
   7 to be interrupted and a new message has to be started.
   8
   9 This could result in repeated or missing entries when the multicast flags
  10 are dumped to userspace.

  12 Fixes: 06c82b7b15b1 ("batman-adv: Add inconsistent multicast netlink dump detection")
