IPv6 Privacy extensions should probably be disabled on that sort of device. They won't work anyway. If userland wants a more usual Ethernet-ish interface with usual IPv6 autoconfiguration, it will use a TAP device with an emulated link-layer and a random hardware address rather than a TUN device. As far as I could fine, TUN virtual device from TUNTAP is the very only sort of device using ARPHRD_NONE as kernel device type.

Simonetti" Date: Mon, 13 Jun 2005 15:19:03 -0700 Subject: [IPV4]: Sysctl configurable icmp error source address. This patch alows you to change the source address of icmp error messages. It applies cleanly to 2.6.11.11 and retains the default behaviour. In the old (default) behaviour icmp error messages are sent with the ip of the exiting interface. The new behaviour (when the sysctl variable is toggled on), it will send the message with the ip of the interface that received the packet that caused the icmp error. This is the behaviour network administrators will expect from a router. It makes debugging complicated network layouts much easier. Also, all 'vendor routers' I know of have the later behaviour.
