+=====================================================
+Notes on the DEC FDDIcontroller 700 (DEFZA-xx) driver
+=====================================================
+
+:Version: v.1.1.4
+
+
+DEC FDDIcontroller 700 is DEC's first-generation TURBOchannel FDDI
+network card, designed in 1990 specifically for the DECstation 5000
+model 200 workstation. The board is a single attachment station and
+it was manufactured in two variations, both of which are supported.
+
+First is the SAS MMF DEFZA-AA option, the original design implementing
+the standard MMF-PMD, however with a pair of ST connectors rather than
+the usual MIC connector. The other one is the SAS ThinWire/STP DEFZA-CA
+option, denoted 700-C, with the network medium selectable by a switch
+between the DEC proprietary ThinWire-PMD using a BNC connector and the
+standard STP-PMD using a DE-9F connector. This option can interface to
+a DECconcentrator 500 device and, in the case of the STP-PMD, also other
+FDDI equipment and was designed to make it easier to transition from
+existing IEEE 802.3 10BASE2 Ethernet and IEEE 802.5 Token Ring networks
+by providing means to reuse existing cabling.
+
+This driver handles any number of cards installed in a single system.
+They get fddi0, fddi1, etc. interface names assigned in the order of
+increasing TURBOchannel slot numbers.
+
+The board only supports DMA on the receive side. Transmission involves
+the use of PIO. As a result under a heavy transmission load there will
+be a significant impact on system performance.
+
+The board supports a 64-entry CAM for matching destination addresses.
+Two entries are preoccupied by the Directed Beacon and Ring Purger
+multicast addresses and the rest is used as a multicast filter. An
+all-multi mode is also supported for LLC frames and it is used if
+requested explicitly or if the CAM overflows. The promiscuous mode
+supports separate enables for LLC and SMT frames, but this driver
+doesn't support changing them individually.
+
+
+Known problems:
+
+None.
+
+
+To do:
+
+5. MAC address change. The card does not support changing the Media
+ Access Controller's address registers but a similar effect can be
+ achieved by adding an alias to the CAM. There is no way to disable
+ matching against the original address though.
+
+7. Queueing incoming/outgoing SMT frames in the driver if the SMT
+ receive/RMC transmit ring is full. (?)
+
+8. Retrieving/reporting FDDI/SNMP stats.
+
+
+Both success and failure reports are welcome.

+1. Overview
+===========
+
+This README explains how to use the driver 'skfp' for Linux with your
+network adapter.
+
+Chapter 2: Contains a list of all network adapters that are supported by
+this driver.
+
+Chapter 3:
+ Gives some general information.
+
+Chapter 4: Describes common problems and solutions.
+
+Chapter 5: Shows the changed functionality of the adapter LEDs.
+
+Chapter 6: History of development.
+
+
+2. Supported adapters
+=====================
+
+The network driver 'skfp' supports the following network adapters:
+SysKonnect adapters:
+
+ - SK-5521 (SK-NET FDDI-UP)
+ - SK-5522 (SK-NET FDDI-UP DAS)
+ - SK-5541 (SK-NET FDDI-FP)
+ - SK-5543 (SK-NET FDDI-LP)
+ - SK-5544 (SK-NET FDDI-LP DAS)
+ - SK-5821 (SK-NET FDDI-UP64)

+ - Netelligent 100 FDDI SAS Fibre SC
+ - Netelligent 100 FDDI DAS UTP
+ - Netelligent 100 FDDI SAS UTP
+ - Netelligent 100 FDDI SAS Fibre MIC
+
+
+3. General Information
+======================
+
+From v2.01 on, the driver is integrated in the linux kernel sources.
+Therefore, the installation is the same as for any other adapter
+supported by the kernel.
+
+Refer to the manual of your distribution about the installation
+of network adapters.
+
+Makes my life much easier :-)
+
+4. Troubleshooting
+==================
+
+If you run into problems during installation, check those items:
+
+Problem:
+ The FDDI adapter cannot be found by the driver.
+
+Reason:
+ Look in /proc/pci for the following entry:
+
+ 'FDDI network controller: SysKonnect SK-FDDI-PCI ...'
+
+ If this entry exists, then the FDDI adapter has been
+ found by the system and should be able to be used.
+
+ If this entry does not exist or if the file '/proc/pci'
+ is not there, then you may have a hardware problem or PCI
+ support may not be enabled in your kernel.
+
+ The adapter can be checked using the diagnostic program
+ which is available from the SysKonnect web site:
+
+ www.syskonnect.de
+
+ Some COMPAQ machines have a problem with PCI under
+ Linux. This is described in the 'PCI howto' document
+ (included in some distributions or available from the
+ www, e.g. at 'www.linux.org') and no workaround is available.
+
+Problem:
+ You want to use your computer as a router between
+ multiple IP subnetworks (using multiple adapters), but
+ you cannot reach computers in other subnetworks.
+
+Reason:
+ Either the router's kernel is not configured for IP
+ forwarding or there is a problem with the routing table
+ and gateway configuration in at least one of the
+ computers.
+
+If your problem is not listed here, please contact our
+technical support for help.
+
+You can send email to: linux@syskonnect.de
+
+When contacting our technical support,
+please ensure that the following information is available:
+
+- System Manufacturer and Model
+- Boards in your system
+- Distribution
+- Kernel version
+
+
+5. Function of the Adapter LEDs
+===============================
+
+ The functionality of the LED's on the FDDI network adapters was
+ changed in SMT version v2.82. With this new SMT version, the yellow
+ LED works as a ring operational indicator. An active yellow LED
+ indicates that the ring is down. The green LED on the adapter now
+ works as a link indicator where an active GREEN LED indicates that
+ the respective port has a physical connection.
+
+ With versions of SMT prior to v2.82 a ring up was indicated if the
+ yellow LED was off while the green LED(s) showed the connection
+ status of the adapter. During a ring down the green LED was off and
+ the yellow LED was on.
+
+ All implementations indicate that a driver is not loaded if
+ all LEDs are off.
+
+
