npu_flag=01 Means only egress ESP packets can be offloaded, ingress ESP packets will be handled by the kernel
npu_flag=02 Means only ingress ESP packets can be offloaded, egress ESP packets will be handled by the kernel
npu_flag=03 Means that both ingress & egress ESP packets will be offloaded

For a fast tunnel npu_flag=03 is essential
