Later patches add support for tunnel offload on Riverhead (EF100). A board can host at most 254 tunnels. Partially offloaded (missed) tunnel packets are identified by virtue of 8 high bits in Rx mark. Add basic definitions of the upcoming tunnel offload support and take care of the dedicated bits in Rx mark across the driver.
