Subject: Get multiple ip addresses by dhcp for wireless card

Hello,

Is it possible for one station to get multiple ip addresses from AP/Wireless
router by dhcp? I had tried to add one or more virtual interface for
phy0 (wlan0, wlan1, wlan2,etc), but only wlan0 can get ip address from AP. 
the following is the steps:

/bin/wpa_supplicant -ddd -iwlan0 -Dnl80211 -c/wifi/wpa_supplicant.conf -B
/bin/wpa_cli -i wlan0 -p /wlan0
>add_network
>set_network 0 ssid "APabc" 
>set_network 0 psk "1111111" 
>enable_network 0

iw wlan0 interface add wlan1 type station 4addr on
ip link set wlan1 up
dhcpcd -ABKL wlan0 #works, can get ip
dhcpcd -ABKL wlan1 #cannot work
