Well I should qualify. 1 Mbit isn't CCK, it's DSSS. 5.5 and 11 are CCK,
or optionally PBCC, but I've seen exactly one AP that might support this
(indicated by supporting 22 Mbit, but not 33).
In practice, the only supported rates at least in mac80211 right now are
DSSS: 1 2
CCK: 5.5 11
OFDM: 6 9 ...
The supported preambles would be ERP and DSSS on 2.4 GHz, and OFDM (does
that preamble even have a specific name?) on 5 GHz, I think.
