This patch adds power management support in mac80211.
This allows us to enable power management through the "iwconfig <device=
> power <off/on>" command.
The code is based on "mac80211-10.0.0" but it is a little bit modified.

Ok, the previous patch had a little error.

This patch adds power management support in mac80211.
This allows us to enable power management through the "iwconfig <device=

-EINVAL seems not right. Doesn't that already return an error code?

Sounds good to me, at least. It would be nice to have PSM support to
mac80211.

Didn't Yi submitted this one like year ago and rejected?
This is why we have currently implemented in iwlwif sysfs.
/sys/class/net/wlanX/devices/power_level
there are defined 6 power levels
0 - CAM mode (Continuous Aware Mode)
6 - AUTO
1 to 5 levels that specifies power save aggressiveness empirically dev=
eloped.
AUTO - depends on system power source/level
system power level is AC or BATTERY - currently we do not have
anything that tells us whether we run on battery or ac.
Other factor is association state.
This can be expressed as
iwconfig power saving 1..5
iwconfig power off - > CAM mode
iwconfig power auto - this is unfortunately not defined by iwconfig
If this acceptable we can submit the patch
Thanks
Tomas

Here is my version then, against your wireless-next tree:
This patch implements the power management routines wireless extensions
for mac80211.
For now we only support switching PS mode between on and off.
