The synthetic target ethernet documentation is very clear on this: "It is not possible for an ethernet device to be shared by both the eCos TCP/IP stack and the Linux one: there would be no simple way to work out which stack incoming packets are intended for. In theory it might be possible to do some demultiplexing using distinct IP addresses, but it would be impossible to support some functionality such as DHCP. Therefore the rawether program will refuse to access any ethernet device already in use. On a typical Linux system eth0 will be used for Linux networking, and the PC will have to be equipped with additional ethernet devices for use by eCos."
