Malo supports the PCMCIA/CF variant of the 8385; not a PCI variant
AFAICT. I know of no PCI variant for the 8385, just CF, SDIO, and GSPI.
But I find it curious that malo supports 8335+8385, given that the
firmware interface of the 8385 and the 8335 are so different. Unless
they have special firmware, the 8385 is a fullmac device, while the 8335
is a softmac device. Enough differences exist that I'd expect them to
be driven by separate drivers, otherwise the code would be quite ugly.
Which is why we didn't try to shoehorn the 8335 or TopDog stuff into
libertas.
