There are two cases here, but in both of them, them PMK (i.e., PSK for
WPA-Personal) needs to be set just before the 4-way handshake would
start. When using WPA-Personal, the PSK would be set just before (or as
part of) association request. When using WPA-Enterprise (WPA-EAP), the
PMK would be set after having completed IEEE 802.1X/EAP authentication
(and the driver/firmware would then take care of 4-way handshake). Both
cases will end up disabling the user space supplicant from taking part
in 4-way handshake, i.e., it will ignore EAPOL-Key frames should they be
delivered through the netdev and expects the driver/firmware to process
them.
