RSN/WPA2 - PMKSA cache in STA and in AP

[Ajeet Nankani]

If STA roams to other AP and makes a new PMKSA with new AP, then does 
STA keep previous PMKSAs which it made with previous AP(s), in its 
cache, if yes for how long and for how many previous APs?

Same question on AP side, that for how long AP keeps PMKSA of STAs which 
associated with it previously but now have been roamed to other APs 
hence are not currently associated with this old AP.
