    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."
