- * The MAC and BSSID addressess are simple array of bytes,
- * these arrays are little endian, so when sending the addressess
- * to the drivers, copy the it into a endian-signed variable.
- *
- * Note that all devices (except rt2500usb) have 32 bits
- * register word sizes. This means that whatever variable we
- * pass _must_ be a multiple of 32 bits. Otherwise the device
- * might not accept what we are sending to it.
- * This will also make it easier for the driver to write
- * the data to the device.
- *
- * Also note that when NULL is passed as address the
- * we will send 00:00:00:00:00 to the device to clear the address.
- * This will prevent the device being confused when it wants
- * to ACK frames or consideres itself associated.
