From 280a9d340057ce1b3cca63084df22f4ef5b35fba Mon Sep 17 00:00:00 2001 From: Masahide NAKAMURA Date: Wed, 23 Aug 2006 19:17:12 -0700 Subject: [PATCH] [IPV6] MIP6: Add socket option and ancillary data interface of routing header type 2. Add socket option and ancillary data interface of routing header type 2. Mobile IPv6 application will use this to send binding acknowledgement with the header without relation of confirmed route optimization (binding). Based on MIPL2 kernel patch.
