All drivers use the same values for TSF sync, this will move the value determination into rt2x00config.c, and the definition for the values to rt2x00reg.h Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* 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.
