Hi, Maintainers

In our scene, we will create the 6in4/6to4 tunnel firstly and need to check the
tunnel type, secondly, we will configure the ip address on it. So, Could we have
any way to get the actual tunnel for 6in4 and 6to4 from current linux version?

Both 6in4 and 6to4 have the same protocol “IPPROTO_IPV6” in Linux kernel. The
only difference is the ip address on the tunnel. Can we distinguish them in
Linux kernel?
Just check the prefix, like it is done in check_6rd().


Regards,
Nicolas
