When STA has around say 10 or more PMKSAs in its cache, and when STA
roams to other AP with which STA has a PMKSA in its cache, then how do
the STA selects which PMKID(s) to send in Re-Association Frame?

Do STA matches new APs BSSID(MAC address) with all the MAC addresses,
STA has in its PMKSA cache and sends the PMKID of the matched one or the
STA sends all PMKIDs it has in its cache?
