In different situations it is possible that the DHCP server or client uses broadcast Ethernet frames to send messages to each other. The GW component in batman-adv takes care of using bat-unicast packets to bring broadcast DHCP Discover/Requests to the "best" server. On the way back the DHCP server usually sends unicasts, but upon client request it may decide to use broadcasts as well. This patch improves the GW component so that it now snoops and sends as unicast all the DHCP packets, no matter if they were generated by a DHCP server or client.
