   4 Subject: [PATCH] batman-adv: only drop packets of known wifi clients
   5
   6 If the source or destination mac address of an ethernet packet
   7 could not be found in the translation table the packet was
   8 dropped if AP isolation was turned on. This behavior would
   9 make it impossible to send broadcast packets over the mesh
  10 as the broadcast address will never enter the translation
  11 table.
