Yeah, I was going to propose that on Friday but got side-tracked.  What
would require a new key type?  Are there some firmwares that _only_
accept the WPA passphrase?  Because if there aren't (PS3 accepts WPA hex
keys too) then the supplicant could just pass the hex key.  Not quite
sure what you mean here with "new key type".

It is a new key type regardless of whether it is PSK or passphrase. The
current key types (IW_AUTH_CIPHER_*) are WEP40, TKIP, CCMP, and WEP104..

Ah, it's a different key because it's not set _during_ the 4-way
handshake, but just sent to the fw directly and the fw handles it,
right?

I don't know whether there are any Linux drivers that would use WPA
passphrase, but at least the Mac OS X driver interface seems to only use
passphrase for WPA-Personal, so it is apparently possible to design such
a architecture ;-). Anyway, I would be fine with just adding
IW_AUTH_CIPHER_PMK for now (and the new capability to figure out whether
this is needed). That PMK would be PSK for WPA-Personal, but it could
also be used as PMK for WPA-Enterprise, so the more generic PMK name.

Sounds good.
