As known, KNI can send requests of changing mtu and configuring the network= if to the dpdk application. I read the howto guide of "Virtio_user as Exceptional Path", Does the solut= ion of virtio_user also support sending the same requests? If support, how to receive the requests and send the response? In the application of testpmd, I cannot find the answer. Thanks Chris ________________________________
