Unfortunately, looks like this patch has no effect regarding the
ARP Request overhead. According to batctl log, DHCPACKs are
snooped, but still 84.3% of all ARP Requests come from the three
DHCP servers / gateways.

These ARP Requests come encapsulated in a batman-adv broadcast
packet type.

Hm, anyone having another idea what might still be causing these
ARP Requests?

Cheers, Linus
