All the NPI boards (that I've seen) use the National Semi. "BMAC",
"PLAYER" and supporting silicon plus a spattering of XILINX FPGAs.

The Cisco/Crescendo use the AMD SuperNET (IIRC) (or earlier MACH
controllers) chipset.  SysKonnect also makes FDDI boards which use this
chipset and they have a little documentation available plus a Linux driver
(I think).

Writing SBUS FDDI drivers would be non-trivial for the NPI and maybe a bit
easier for the AMD based boards.
