/* Default noise level to report when noise measurement is not available.
* This may be because we're:
* 1) Not associated no beacon statistics being sent to driver)
* 2) Scanning (noise measurement does not apply to associated channel)
* Use default noise value of -127 ... this is below the range of measurable
* Rx dBm for all agn devices, so it can indicate "unmeasurable" to user.
* Also, -127 works better than 0 when averaging frames with/without
* noise info (e.g. averaging might be done in app); measured dBm values are
* always negative ... using a negative value as the default keeps all
* averages within an s8's (used in some apps) range of negative values. */
