    I am using wpa_supplicant 0.3.2.
    I can associated and authenticated with my AP with WPA/TKIP/1X-KEY-MGMT.
    The hosts that at wired side can send packets to my FreeBSD station, but
    wired hosts can not receive any station's packets.
    Then, I use AiroPeek to capture wireless packets. I saw that any data
    packet sent by wired side is encrypted, and station can decrypte that
    well.
    When station reply or send any packet it is not encrypted, at this time
    AP may drop the packet.
