Hello.

In article <9c46321e0712040727tee578cm97a83936fefb34ed@...l.gmail.com> (at Tue, 4 Dec 2007 16:27:50 +0100), "Hugo Santos" <hugosantos@...il.com> says:

What do you mean by "ipv6 header"?

I think hdrincl is broken (and even, say, deprecated) on IPv6.

If we do really support it, if hdcincl is set, XFRM and other
all extension header processes should be skipped, but they are
not very clear at all so far.
