This makes it somewhat easier for the station to be able to receive and process the encrypted WNM-Notification frames that the AP previously sentt immediately after receiving EAPOL-Key msg 4/4. While the station is supposed to have the TK configured for receive before sending out EAPOL-Key msg 4/4, not many actual implementations do that. As such, there is a race condition in being able to configure the key at the station and the AP sending out the first encrypted frame after EAPOL-Key 4/4. The extra 100 ms time here makes it more likely for the station to have managed to configure the key in time. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
