Scott Feldman d0d2555852 rocker: mark copy-to-cpu pkts as forwarding offloaded
For pkts copied to the CPU (to be processed by guest driver), mark the Rx
descriptor with flag "OFFLOAD_FWD" to indicate device has already forwarded
pkt.  The guest driver will use this indicator to avoid duplicate
forwarding in the guest OS.

Examples include bcast/mcast/unknown ucast pkts flooded to bridged ports.
We want to avoid both the device and the guest bridge driver flooding these
pkts, which would result in duplicates pkts on the wire.  Packet sampling,
such as sFlow, can also use this technique to mark pkts for the guest OS to
record but otherwise drop.
