The indication to calculate the GRE checksum is currently the port
config rather than the tunnel flow. Currently there is a one to one
mapping between the two so there is no difference. However, the
kernel datapath must use the flow and it is also potentially more
flexible, so this switches how we decide whether to calculate the
checksum.
