Netmap/vale attempts to speed up network communication by bypassing the TCP/IP network stack, which requires patching the physical NIC driver so that applications developed based on netmap can interact directly with the physical NIC driver. It may make sense for some specific scenarios which requres very high bandwith (10Gb/s or 100Gb/s), we can even put up with the complexity and compatibility introduced by this techology. However for ACRN, a virtualization solution for IoT, there is no need to support this backend. For 1Gb NICs or below, the VBS-U/tap solution can already achieve near-native bandwidth. To keep simplicity and improve compatibility, remove the netmap/vale support in dm.
