#   [XFRM]: Always reroute in tunnel mode
#   
#   Tunnel mode packets are rerouted if the tunnel destination
#   address is different from the original destination address,
#   otherwise the old route is used. This is inconsistent, the
#   old route might have been selected for a given output device
#   or using routing by tos/fwmark. Always choose a new route
#   in tunnel mode.
