@-i: interface name: eth1
@-c: Configuration file: wpa_supplicant_psk.conf
@-D: The name of network interface.
You will see the following message if wpa-psk connection is built successfully.
...
WPA: Sending EAPOL-Key 2/2 ---> The Group handshake is about to finish.

EAPOL: SUPP_PAE entering state SUCCESS
EAP: EAP entering state SUCCESS
EAPOL: SUPP_PAE entering state AUTHENTICATED
EAPOL: SUPP_BE entering state IDLE
Note of wpa supplicant operation issue:
The WPA supplicant should be keep running during connection. If you press
Ctrl-C to stop the wpa supplicant, it will also close the network interface card
by "zd1205_close" call back routine. So you have to issue ifconfig ethx up again
before using the network interface card.
3.7 Customization of VID/PID Table
Someone may want to drive any NIC with XG-762N chipset. But, if its VID/PID isn¡¯t
listed in the driver, the linux kernel won¡¯t load the XG-762N driver to serve the device.
You can add the device¡¯s VID/PID to the driver source. Then, the kernel will load driver
next time you plug the USB dongle.
In the source file, src/zdusb.c, A static structure, XG-762N_ids, stores the VID/PID list of
supported products. You can add your dongle¡¯s VID/PID here. Then, remake, install the
driver and plug the dongle. You will see it works now.
3.8 Special Mode for Embedded Station Chariot Test
In an embedded system, mostly, there is no NetIQ chariot endpoint, for WiFi testing,
to test performance. With this mode, we can bridge the Ethernet and WLAN. The PC
behind the Ethernet runs endpoint and testing data go through the station¡¯s wireless
interface to measure the performance.
The mechanism is to specify the MAC address for association with AP. Generally,
we associate with AP using the station¡¯s MAC address. If we bridge the wired and
wireless interfaces, data from wired interface will be dropped by AP. Because PC¡¯s MAC
address is filled in source address of data frames. AP drops the frames because the source
address is not in associated stations list. If we can use AP¡¯s address for association, we
can run chariot on PC to test station wireless interface performance. This is just like what
we do in AP mode.
Someone may say that "Can¡¯t I just set station¡¯s MAC as PC¡¯s via ifconfig ethX hw
ether". Yes, perhaps, you can. But most bridge will drop the data when the source address
is identical to its interfaces¡¯. Therefore, we must let the address for association and
