Hi,

The only dubious case is when next hop is set using routing tables.
But code in ipgre_tunnel_xmit() is ready to accept this situation,
it checks for zero destination address and fixes it when it is able to.
Nevertheless, it does not work.
Another thoughts?
Could you explain this a little more?
I was able to set a nbma gre tunnel, add routes to it and it worked
perfectly ok.
Link-level next hop worked:
ip route add <route> via <link-level-address> dev <tunnel-dev> onlink
Also normal route with static neighbor worked:
ip neigh add <router-tunnel-ip> lladdr <link-level-address> nud permanent dev
<tunnel-dev>
ip route add <route> via <router-tunnel-ip>
In both cases packets were routed as expected to hosts accessible using
the added route. And sendto() sent a packet correctly with destination
link-level-address set. Did I miss/misunderstand something?
Cheers,
Timo
