From 75f2811c6460ccc59d83c66059943ce9c9f81a18 Mon Sep 17 00:00:00 2001 From: Jesse Gross Date: Wed, 30 Nov 2011 17:05:51 -0800 Subject: ipv6: Add fragment reporting to ipv6_skip_exthdr(). While parsing through IPv6 extension headers, fragment headers are skipped making them invisible to the caller. This reports the fragment offset of the last header in order to make it possible to determine whether the packet is fragmented and, if so whether it is a first or last fragment.
