Are you proactively sending keep alive messages from the driver or the fw? what's wrong with the probes sent by the kernel NUD subsystem? In our driver we also update the used value for neighs of offloaded tunnels, we do it based on flow counters for the offloaded tunnels which is an evidence for activity. Any reason for you not to apply a similar practice? Or.
