First of all, this is only used if the driver/card takes care of WPA/RSN
IE generation for (Re)Association Request frames and roaming selection.

These commands are used to add/remove entries to the PMKSA cache in the
driver, or well, to be more exact, to add BSSID,PMKID pairs, i.e., just
part of the PMKSA entry. The driver will need to maintain this table and
whenever it generates an RSN IE to a (Re)Association Request frame, it
should add PMKID into it if the destination BSSID is found in the PMKSA
table. This is only used with WPA2.
