A DCF (Device Config Function) based approach is proposed where a device bound to the device's VF0 can act as a sole controlling entity to exercise advance functionality (such as switch, ACL) for rest of the VFs.
The DCF works as a standalone PMD to support this function, which shares the ice PMD flow control core function and the iavf virtchnl mailbox core module. This patchset is based on: [1] https://patchwork.dpdk.org/cover/66417/ update ice base code And it needs the coming iavf common lib update to compile, the modified ice flow function to work.
