From c61a404325093250b676f40ad8f4dd00f3bcab5f Mon Sep 17 00:00:00 2001 From: Masahide NAKAMURA Date: Wed, 23 Aug 2006 19:18:35 -0700 Subject: [IPV6]: Find option offset by type. This is a helper to search option offset from extension header which can carry TLV option like destination options header. Mobile IPv6 home address option will use it. Based on MIPL2 kernel patch.

In receiving Mobile IPv6 home address option which is a TLV carried by destination options header, kernel will try to mangle source adderss of packet. Think of cloned skbuff it is required to replace it by the parser just like routing header case. This is a framework to achieve that to allow TLV parser to replace inbound skbuff pointer.
