-Subject: batman-adv: Fix speedy join in gateway client mode
-
-Speedy join only works when the received packet is either broadcast or an
-4addr unicast packet. Thus packets converted from broadcast to unicast via
-the gateway handling code have to be converted to 4addr packets to allow
-the receiving gateway server to add the sender address as temporary entry
-to the translation table.
-
-Not doing it will make the batman-adv gateway server drop the DHCP response
-in many situations because it doesn't yet have the TT entry for the
-destination of the DHCP response.
