What is the fastpath? Where do you offload any configuration that actually ensures VF<->physical_port and VF<->VF traffic? There should be some bridge/tc/route offload. Or, what I fear, do you use some implicit mac-based steering? If yes, you should not. In switchdev mode, if user does not configure representors to forward packets, there is no packet forwarding.

This series adds representor support for each rvu devices. When switchdev mode is enabled, representor netdev is registered for each rvu device. In implementation of representor model, one NIX HW LF with multiple SQ and RQ is reserved, where each RQ and SQ of the LF are mapped to a representor. A loopback channel is reserved to support packet path between representors and VFs. CN10K silicon supports 2 types of MACs, RPM and SDP. This patch set adds representor support for both RPM and SDP MAC interfaces. - Patch 1: Refactors and exports the shared service functions. - Patch 2: Implements basic representor driver. - Patch 3: Add devlink support to create representor netdevs that can be used to manage VFs. - Patch 4: Implements basec netdev_ndo_ops. - Patch 5: Installs tcam rules to route packets between representor and VFs. - Patch 6: Enables fetching VF stats via representor interface - Patch 7: Adds support to sync link state between representors and VFs . - Patch 8: Enables configuring VF MTU via representor netdevs. - Patch 9: Add representors for sdp MAC. - Patch 10: Add devlink port support. Command to create PF/VF representor #devlink dev eswitch set pci/0002:1c:00.0 mode switchdev VF representors are created for each VF when switch mode is set switchdev on representor PCI device. Each PF support upto 3VFs.
