From e1c511199715b9ef85f537fbd01f6cdfd050d433 Mon Sep 17 00:00:00 2001 From: Steven Barth Date: Thu, 23 Jan 2014 10:59:04 +0000 Subject: [PATCH] 6rd: Make don't fragment bit (df) a configurable variable Make the IPv4 "do not fragment" bit a configurable variable for the 6rd tunnel interface as the bit should not be set in the encapsulating IPv4 header according to RFC3056. On top the config variable allows to enable/disable path mtu discovery for tunnel interfaces. Config variable can be passed to netifd as tunnel config support is already present for the "do not fragment" bit.
