These patches propose a way to adjust the dynamic ps timeout in the mac80211
based on the pm-qos network latency value. This allows user space to influence
the level of power saving performed by the mac80211.
These patches will the current 100ms timeout for the default network
latency value (2000s), so that for non-adjusted pm-qos the functionality will
remain as it is currently. Dynamic ps is disabled for any larger latency
values, and a timeout of 300s is used for latency values smaller than 50ms.
v3 of these patches ad a 50s dynamic ps configuration.
As wext still has an interface to adjust the dynamic ps timeout from userspace,
the wext configuration will override the above, to remain backwards
compatible.
Comments are appreciated.
