ORBIT-USER: Atheros 802.11 metrics

[Kishore Ramachandran]

Hi Tashina:

> Are the cw values set by card or by the type of 802.11 network used?
They are set by the driver depending on the type of network (802.11a/b/g) 
according to the standard. These values are configurable since they are 
set in the driver.

regards,
Kishore
