rtls(7D) Devices rtls(7D) NAME
rtls - Realtek Fast Ethernet 8139-based network interface controllers SYNOPSIS
/dev/rtls DESCRIPTION
The rtls Ethernet driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface, dlpi(7P), over Realtek 8139 controllers. The rtls driver provides basic support for the Realtek 8139 hardware. Functions include chip initialization, frame transmit and receive, multicast support, and error recovery and reporting. APPLICATION PROGRAMMING INTERFACE
The cloning, character-special device /dev/rtls is used to access all 8139 devices installed within the system. rtls and DLPI The rtls driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the rtls driver with the DLPI and STREAMS func- tionality required of a LAN driver. See gld(7D) for more details on the primitives supported by the driver. The values returned by the driver in the DL_INFO_ACK primitive in response to the DL_INFO_REQ from the user are as follows: o Maximum SDU is 1500 (ETHERMTU). o Minimum SDU is 0. The driver pads to the mandatory 60-octet minimum packet size. o The dlsap address length is 8. o MAC type is DL_ETHER. o The sap length value is -2, meaning the physical address component is followed immediately by a 2-byte sap component within the DLSAP address. o Broadcast address value is Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF). KNOWN PROBLEMS AND LIMITATIONS
The rtls driver only supports Realtek 8139 on x86 platforms. The rtls driver does not support the NDD interface and MII statistics. Realtek 8139 works under 100FDX/100HDX and 10FDX/10HDX modes, which you can set using the rtls.conf file. CONFIGURATION
To configure the rtls driver: o Use prtconf -v | grep pci10ec,8139 to obtain the instance number of the driver. (pci1186,1301 or pci1113,1211 indicates a third-party ethernet device with an 8139 chip that can also be controlled by the rtls driver.) The rtls.conf configuration file options include: -ForceSpeedDuplex Default: 5 (Auto-negotiate) Allowed Values: 4 (100 FDX) 3 (100 HDX) 2 (10 FDX) 1 (10 HDX) Specify the speed and duplex mode for each instance. Example: ForceSpeedDuplex=5,4; Sets rtls0 to autonegotiate and rtls1 to 100 FDX. FILES

dnet(7D) Devices dnet(7D) NAME
dnet - Ethernet driver for DEC 21040, 21041, 21140 Ethernet cards SYNOPSIS
/kernel/drv/dnet DESCRIPTION
The dnet Ethernet driver is a multithreaded, loadable, clonable, STREAMS GLD driver. Multiple controllers installed within the system are supported by the driver. The dnet driver functions include controller initialization, frame transmit and receive, functional addresses, promiscuous and multicast support, and error recovery and reporting. APPLICATION PROGRAMMING INTERFACE
The cloning character-special device, /dev/dnet, is used to access all DEC 21040/21041/21140 devices installed in the system. The dnet driver is dependent on /kernel/misc/gld, a loadable kernel module that provides the dnet driver with the DLPI and STREAMS func- tionality required of a LAN driver. See gld(7D) for more details on the primitives supported by the driver. The device is initialized on the first attach and de-initialized (stopped) on the last detach. The values returned by the driver in the DL_INFO_ACK primitive in response to a DL_INFO_REQ from the user are as follows: o The maximum SDU is 1500 (ETHERMTU - defined in <sys/ethernet.h>). o The minimum SDU is 0. o The DLSAP address length is 8. o The MAC type is DL_ETHER. o The sap length value is -2, meaning the physical address component is followed immediately by a 2-byte sap component within the DLSAP address. o The broadcast address value is the Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF). Once in the DL_ATTACHED state, the user must send a DL_BIND_REQ to associate a particular Service Access Point (SAP) with the stream. PRECONFIGURATION
The PCI configuration process varies from system to system. Follow the instructions provided by the vendor. Known Problems and Limitations o On multiport cards (exception: Osicom (Rockwell) RNS2340), the first port is the top port. (On the Osicom RNS2340, the first port is the bottom port.) o If the dnet driver fails to determine the correct speed and duplex mode resulting in a corresponding drop in performance, set the speed and duplex mode using the dnet.conf file. o The dnet driver incorrectly counts carrier lost or no carrier errors while in full-duplex mode. There is no carrier signal present when in full-duplex mode and it should not be counted as an error. o Version 4 SROM formats are not supported. CONFIGURATION
The /kernel/drv/dnet.conf file supports the following options: full-duplex For full duplex operation use full-duplex=1, for half duplex use full-duplex=0. Half-duplex operation gives better results on older 10mbit networks. speed For 10mbit operation use speed=10, for 100mbit operation use speed=100. Certain 21140 based cards will operate at either speed. Use the speed property to override the 100mbit default in this case. FILES
