Thank you very much. Another related question is: When a wireless interface works in master mode with new firmware "fw_bcm4329_apsta.bin" launched, is there any way to set power mode to PM_OFF, PM_FAST, PM_MAX? My ultimate goal is to let the interface to sleep even in master mode. Right now, I try to use "dev_wlc_ioctl(dev, WLC_SET_PM, &pm, sizeof(pm))", but it doesn't work. BTW, my test device is Nexus One and the broadcom driver is BCM4329.
