Similarly to the offload_fwd_mark field, the offload_mr_fwd_mark field is
used to allow partial offloading of MFC multicast routes.

The reason why the already existing "offload_fwd_mark" bit cannot be used
is that a switchdev driver would want to make the distinction between a
packet that has already gone through L2 forwarding but did not go through
multicast forwarding, and a packet that has already gone through both L2
and multicast forwarding.

Hi Jiri

So we are talking about l2 vs l3. So why not call this
offload_l3_fwd_mark?

Is there anything really specific to multicast here?

   Thanks
