Change MAC address of "wlan0"
I tested this at rooted LG Optimus-Q.
Run this program under root shell.
Usage)chmac- display MAC address of wlan0chmac 00:11:22:33:44:55- change MAC address of wlan0 to 00:11:22:33:44:55
I modified the code from http://dev.odroid.com/projects/chmac for wlan0. The original code used eth0.
