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. - -Maciej W. Rozycki <macro@linux-mips.org> |
