batman-adv: send every DHCP packet as bat-unicast
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.
