commit 12c771df4b9c200ea0b53886c3a0939a16097c02 Author: Sven Eckelmann sven@narfation.org Date: Sun Jun 12 10:43:19 2016 +0200
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.
