Ack. This is good idea. Frankly, I was sure ip_gre worked in this way all these years. I do not remember any reasons why it was crippled. 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.
