Subject: 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.
