From 327c711da495483099a30e3f80e0fd8a85e8192d Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Tue, 29 May 2018 15:31:21 +0200 Subject: [PATCH] odhcp6c: make ds-lite/map 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 for dynamic created ds-lite/map interfaces. Setting the uci parameter encaplimit_dslite/map to ignore; allows to disable the insertion of the destination option header for the dynamic created ds-lite/map interface. Otherwise the tunnel encapsulation limit value can be set to a value from 0 till 255 by setting the encaplimit_dslite/map uci parameter accordingly.
