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..

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.
