Ivan Malov 53a8051264 net/sfc: fence off 8 bits in Rx mark for tunnel offload
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.
