Add tc-flower support for VF port representor devices. Implement ndo_setup_tc callback for TC HW offload on VF port representors devices. Implemented both methods: add and delete tc-flower flows. Mark NETIF_F_HW_TC bit in net device's feature set to enable offload TC infrastructure for port representor. Implement TC filters replay function required to restore filters settings while switchdev configuration is rebuilt.
