[gpm] Preference option for adjusting wifi power

[satanand burla <satanand burla gmail com>]

Hi,
           Is there any plan to add wifi power management to gnome power manager preferences ? For example, on battery turn on wifi power mgmt, equivalent to doing iwconfig wlan0 power on). Or should wifi power control be the business of  networkmanager ?

            These days linux  mac80211 stack has a number of options for wifi power management, there is a power timeout, there is old style PS Poll and new APSD/UAPSD. These can be configured using ioctls or iw or iwconfig.

            This will add at least a Watt of power savings (of course at the cost of thruput)  as shown by powertop. Popular cards like Atheros and Intel already support power mgmt well. 

            I can sumbit a patch if anybody is interested.

Regards,
Satanand.
