说明：  MAVLink路由器和防火墙。它可以通过串行和UDP连接2个或更多MAVLink端点，如自动驾驶仪，地面控制软件，记录仪，图像捕获系统等。当MAVLink数据包具有目标地址时，它们将路由到特定组件。可以基于源系统/组件，目标系统/组件和消息类型来过滤任何目标或广播的分组。过滤器还可以对数据包应用优先级，允许更多重要数据包在端点被阻塞时优先于较低优先级数据包。(A MAVLink router and firewall. It can connect 2 or more MAVLink endpoints such as autopilots, ground control software, loggers, image capture systems, etc over serial and UDP. MAVLink packets will be routed to specific components when they have a destination address. Any packet, targeted or broadcasted, can be filtered based on source system/component, destination system/component and message type. The filter can also apply a priority to packets allowing more important packets to take priority over lower priority packets when an endpoint is choked.)
