61414f5e - FDDI: defza: Add support for DEC FDDIcontroller 700 TURBOchannel adapter

Tue, 09 Oct 2018 22:57:43 +0000

FDDI: defza: Add support for DEC FDDIcontroller 700 TURBOchannel adapterAdd support for the DEC FDDIcontroller 700 (DEFZA), Digital EquipmentCorporation's first-generation FDDI network interface adapter, made forTURBOchannel and based on a discrete version of what eventually becameMotorola's widely used CAMEL chipset.The CAMEL chipset is present for example in the DEC FDDIcontrollerTURBOchannel, EISA and PCI adapters (DEFTA/DEFEA/DEFPA) that we supportwith the `defxx' driver, however the host bus interface logic and thefirmware API are different in the DEFZA and hence a separate driver isrequired.There isn't much to say about the driver except that it works, but thereis one peculiarity to mention. The adapter implements two Tx/Rx queuepairs.Of these one pair is the usual network Tx/Rx queue pair, in this caseused by the adapter to exchange frames with the ring, via the RMC (RingMemory Controller) chip. The Tx queue is handled directly by the RMCchip and resides in onboard packet memory. The Rx queue is maintainedvia DMA in host memory by adapter's firmware copying received datastored by the RMC in onboard packet memory.The other pair is used to communicate SMT frames with adapter'sfirmware. Any SMT frame received from the RMC via the Rx queue must bequeued back by the driver to the SMT Rx queue for the firmware toprocess. Similarly the firmware uses the SMT Tx queue to supply thedriver with SMT frames that must be queued back to the Tx queue for theRMC to send to the ring.This solution was chosen because the designers ran out of PCB space andcould not squeeze in more logic onto the board that would be required tohandle this SMT frame traffic without the need to involve the driver, aswith the later DEFTA/DEFEA/DEFPA adapters.Finally the driver does some Frame Control byte decoding, so to avoidmagic numbers some macros are added to .Signed-off-by: Maciej W.
