While each packet that is sent to a representor will be received by the VF. This is very useful in case of SRIOV mode, where the first packet that is sent by the VF will be received by the DPDK application which will decide if this flow should be offloaded to the E-Switch. Representor shares interrupts handler with host PF over the PCI address. Therefore, after PF completes its interrupts handler initialization, no additional actions required for representor.
