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. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
