   4 Subject: [PATCH] net: dsa: b53: Fix valid setting for MDB entries
   5
   6 When support for the MDB entries was added, the valid bit was correctly
   7 changed to be assigned depending on the remaining port bitmask, that is,
   8 if there were no more ports added to the entry's port bitmask, the entry
   9 now becomes invalid. There was another assignment a few lines below that
  10 would override this which would invalidate entries even when there were
  11 still multiple ports left in the MDB entry.
