If you want more coverage here, IEEE 802.11r-2008 adds 00-0F-AC:3 (FT
authentication negotiated over IEEE 802.1X) and 00-0F-AC:4 (FT
authentication using PSK). Please note that these are defined only for
OUI 00-0F-AC, though.
In addition, IEEE 802.11w will be adding 00-0F-AC:5 (IEEE 802.1X or
PMKSA caching with SHA256 Key Derivation) and 00-0F-AC-6 (PSK with
SHA256 Key Derivation).

These default are correct for WPA IE, but not for RSN IE/WPA2. However,
it looks like this function is used for both and as such, the WPA2 case
should print out CCMP here (and same below if only the pairwise cipher
suite field is omitted).
In addition, this could show the default AKM value (IEEE 802.1X) if it
is not included in the IE.
