From 2af5cfe9b748914b49f3a157addb40ad7a200e62 Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Tue, 29 May 2018 15:18:16 +0200 Subject: ds-lite: make tunnel encapsulation limit support configurable (FS#1501) Be compatible with ISPs which don't support the destination option header containing the tunnel encapsulation limit as reported in FS#1501. Setting the uci parameter encaplimit to ignore; allows to disable the insertion of the destination option header in the ds-lite packets. Otherwise the tunnel encapsulation limit value can be set to a value from 0 till 255 by setting the encaplimit uci parameter accordingly. If no encaplimit value is specified the default value is 4 as before.
