From 944f548d10c5352ff7b22ef53d1eb61d0f433784 Mon Sep 17 00:00:00 2001 From: Ole Troan <ot@cisco.com> Date: Tue, 24 May 2016 11:56:58 +0200 Subject: IPv6 HBH: Refactor code. Separate out RFC2460 HBH handling and the more experimental IOAM code. Support dynamically adding options. By default only process HBH if explicitly configured to. Otherwise we'll just set ourselves up to be a victim of DOS.
