ip6_tunnel: Match to ARPHRD_TUNNEL6 for dev type [ Upstream commit b2e54b09a3d29c4db883b920274ca8dca4d9f04d ] The device type for ip6 tunnels is set to ARPHRD_TUNNEL6. However, the ip4ip6_err function is expecting the device type of the tunnel to be ARPHRD_TUNNEL. Since the device types do not match, the function exits and the ICMP error packet is not sent to the originating host. Note that the device type for IPv4 tunnels is set to ARPHRD_TUNNEL. Fix is to expect a tunnel device type of ARPHRD_TUNNEL6 instead. Now the tunnel device type matches and the ICMP error packet is sent to the originating host.
