- 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.
