Cool! I planned it recently, but it never happened :-)
BTW, I think the MI SONIC driver should also be shared with
mac68k and newsmips, then I have some questions:
1) Some SONIC boards for mac68k uses 16-bit mode.
(see mac68k/dev/if_snvar.h) How is it handled in your driver?
2) It seems that the AP-bus SONIC for newsmips can only transfer
data into/from on-board memory. How should we handle this?
Should we implement special bus_dma(9) functions for it
to perform bounce buffer?
Anyway, I can test your driver on my Express5800/230.
