    description "
        The USB slave ethernet package supports the development
        of USB peripherals which provide an ethernet service to
        the host machine. Such a peripheral could be a simple
        USB-ethernet converter, or it could be rather more
        complicated internally."

        description "
            The primary purpose of USB slave ethernet support is to provide
            an ethernet service to the USB host. This is very different
            from a conventional network driver which provides a service
            to a TCP/IP stack running inside the peripheral. If this
            component is enabled then the USB-ethernet code will implement
            an eCos network driver, thus supporting both a host-side TCP/IP
            stack and an eCos stack. This raises issues such as enabling
            the bridge code in the stack, and the package documentation
            should be consulted for further information."

                outgoing packets. These statistics are intended mainly
