Hi,
Just a little RFC patchset. Still some work to do, but works as a proof-of-concept for now. With two VMs, I was able to see the DAT Cache filling up with sane entries even when ARP was disabled on the bat0 interfaces.
Will need to check in a larger setup though, whether it has the desired performance gain / overhead reduction.
Let me know what you think about the concept.
Regards, Linus
