Subject: [ 118/187] mwifiex: fix WPS eapol handshake failure

From: Greg KH <gregkh@...uxfoundation.org>

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stone Piao <piaoyun@...vell.com>

commit f03ba7e9a24e5e9efaad56bd1713b994ea556b16 upstream.

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.
