| You can specify the packet size (excluding the link-layer header) using the ''%%--mtu%%'' option. If no packet size is specified, then the default Ethernet size of 1500 bytes will be used. | You can specify the packet size (excluding the link-layer header) using the ''%%--mtu%%'' option.

| + | Some USB drivers may fail to correctly transmit or receive packets that have a length (inclusive of the 14-byte Ethernet link-layer header and any device-specific headers) which is an exact multiple of the USB bulk endpoint MTU (typically 512 bytes). These drivers should be fixed. | ||
