Hi Dan,
In "struct cfg80211_ops" (cfg80211.h) a "set_power_mgmt" handler is defined for IEEE Power Save.
---
* @set_power_mgmt: Configure WLAN power management. A timeout value of -1
* allows the driver to adjust the dynamic ps timeout value.
int (*set_power_mgmt)(struct wiphy *wiphy, struct net_device *dev,
bool enabled, int timeout);
---
And the corresponding iw command is "set power_save on|off".
Currently 'ath6kl', 'iwmc3200wifi', 'rndis_wlan', and 'mwifiex' drivers have implemented the set_power_mgmt callback function for power saving handling.
Do you think if we should add new ops for auto deep sleep?
Thanks,
Bing
