From 1c56c3d2530c6bbf7630dacb0506310ceefdc83a Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Wed, 17 Oct 2018 11:02:05 +0200 Subject: [PATCH] gre: make encaplimit support configurable Make inclusion of the destination option header containing the tunnel encapsulation limit configurable for IPv6 GRE packets. Setting the uci parameter encaplimit to ignore; allows to disable the insertion of the destination option header in the IPv6 GRE packets. Otherwise the tunnel encapsulation limit value can be set to a value from 0 till 255 by setting the encaplimit uci parameter accordingly.
