Maciej W. Rozycki 61414f5ec9 FDDI: defza: Add support for DEC FDDIcontroller 700 TURBOchannel adapter ... Add support for the DEC FDDIcontroller 700 (DEFZA), Digital Equipment Corporation's first-generation FDDI network interface adapter, made for TURBOchannel and based on a discrete version of what eventually became Motorola's widely used CAMEL chipset. The CAMEL chipset is present for example in the DEC FDDIcontroller TURBOchannel, EISA and PCI adapters (DEFTA/DEFEA/DEFPA) that we support with the `defxx' driver, however the host bus interface logic and the firmware API are different in the DEFZA and hence a separate driver is required. There isn't much to say about the driver except that it works, but there is one peculiarity to mention. The adapter implements two Tx/Rx queue pairs. Of these one pair is the usual network Tx/Rx queue pair, in this case used by the adapter to exchange frames with the ring, via the RMC (Ring Memory Controller) chip. The Tx queue is handled directly by the RMC chip and resides in onboard packet memory. The Rx queue is maintained via DMA in host memory by adapter's firmware copying received data stored by the RMC in onboard packet memory. The other pair is used to communicate SMT frames with adapter's firmware. Any SMT frame received from the RMC via the Rx queue must be queued back by the driver to the SMT Rx queue for the firmware to process. Similarly the firmware uses the SMT Tx queue to supply the driver with SMT frames that must be queued back to the Tx queue for the RMC to send to the ring. This solution was chosen because the designers ran out of PCB space and could not squeeze in more logic onto the board that would be required to handle this SMT frame traffic without the need to involve the driver, as with the later DEFTA/DEFEA/DEFPA adapters. Finally the driver does some Frame Control byte decoding, so to avoid magic numbers some macros are added to <linux/if_fddi.h>. Signed-off-by: Maciej W.
