From: Xinying Yu <[email protected]> Create the relay vring on host and then set the address of Rx used ring to the VF config bar. So the device can DMA the used ring information to host rather than directly to VM. Use 'NFP_NET_CFG_CTRL_LM_RELAY' notify the device side. And enable the MSIX interrupt on device. Tx ring address is not needed to change since the relay vring only assists Rx ring to do the dirty page logging.
