Although, README says, that they don't use anything AMBA-specific. Probably SIBA can be hacked up at least for PCI case. Actually, I've started playing with Linux version of the driver[2], it's opensource and dual-licensed, but code seem to me very tangled. (Code of the bus part is GPL-only) Can you recommend any papers about wireless drivers in general? Particularly, I'm interested in working with PHY/ratetables.
