Re: [INET] Add flags field to ip_tunnel_parm

In article [ref] (at Tue, 14 Sep 2004 22:16:17 +1000), Herbert Xu [off-list ref] says:

BTW if anyone else wants to add more fields to the structure, now is
the time.

Well, you simply cannot do this.

Kernel will get garbage from old binaries,
and kernel will break user space if it tries 
to get params into old structure.

So, please change SIOxxxTUNNEL values to support both interfaces
(or give up ioctl and use rtnetlink instead!)

Thanks.
