mac80211: extend/document powersave API
This modifies hardware flags for powersave to support three different flags: * IEEE80211_HW_SUPPORTS_PS - indicates general PS support * IEEE80211_HW_PS_NULLFUNC_STACK - indicates nullfunc sending in software * IEEE80211_HW_SUPPORTS_DYNAMIC_PS - indicates dynamic PS on the device It also adds documentation for all this which explains how to set the various flags. Additionally, it fixes a few things: * a spot where && was used to test flags * enable CONF_PS only when associated again Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
