    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."

                The USB network device driver can maintain some statistics

                about traffic, for example the number of incoming and

                outgoing packets. These statistics are intended mainly

                for SNMP agent software."
