Hi Antonio,
have you tried applying this patch on one of your servers and measure the local effect? (i.e. if the number of BRD ARP req is reduced or not?)
I had queried Martin Weinelt just yesterday, they will test it on a 500 nodes compat-v15 setup soon :).
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?
have you tried enabling DAT debug and observing step by step what happens ? You could try to study a simple case: i.e. an unknown client that comes and connects for the first time..you can save the full log somewhere and then we can all have a look (knowing the MAC address of this client)
Cheers,
