okay, cool > In switchdev mode, broadcasts from VFs are received by the PF and passed > to corresponding port representor netdev. not following. If a VF sends a packet and it doesn't match any HW steering rule, then it has to meet some default rule. Such rule can be fwd to host CPU or drop or something else. E.g in mlx5 currently it's fwd to CPU --> the packet is delivered to the HW queue of the corresponding VF rep is received into the host networking stack from there (the VF rep does netif_rx). In this series you are not doing any offloading, right? so 100% of the packets sent by VFs should meet your default rule which I assume you want to be fwd to host CPU (--> vf rep) Is that broadcast a special case which will remain in place also when you add fdb/tc offloading? why not let the HW steering configuration for all types of traffic be dictated by offloading some SW switching rules? FWIW - I will not be online till Tues, so will see you reply only then Or.
