Well it's some time ago since I read about Soft|Hard|Free|FullMAC for prism
chipsets. Dunno whether there was a way to run even fullmac cards with a
softmac stack.
A much more interesting point: where is the firmware to download to our
Atheros-chip. (NO, no flamewar on free firmware|no firmware again!). Just a
simple question: do we have any way to reflash the FW?
