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.
