Description

Unlike Unicast-packets, which have an ARQ-mechanism on the 802.11 layer to retransmit packets packets, broadcast-packets are only sent once. Consequently the unicast packet loss might be very low and the network will appear will pretty stable, but broadcast-packets (like DHCP, ARP) will hardly reach their destination in worst case scenarios.

Options are for example to just send the broadcast packets multiple times (batman nodes will notice and drop the duplicates in any way) to increase the probability that the broadcast packets are received.

(this is just a reminder for ourselves to fix this problem ;)
