After association, STA will go through eapol handshake with WPS enabled AP. It's observed that WPS handshake fails with some 11n AP. The reason for the failure is that the eapol packet is sent via 11n frame aggregation. The eapol packet should be sent directly without 11n aggregation. This patch fixes the problem by adding WPS session control while dequeuing Tx packets for transmission.
