Thank you very much for your information, it make it a bit clearer how
services offload actually works.

However, I am still wondering if all traffic is eligible for services
offload. Multicast traffic with fan-out > 1 is not, but that is not a
large concern for me. Is there any other traffic which cannot be
offloaded?
