This is because we set this bit depending on the nonpeer_pm variable of the mesh iface sdata and when there are no active links on the interface it remains to NL80211_MESH_POWER_UNKNOWN. As soon as links starts to be established, it wil switch to NL80211_MESH_POWER_ACTIVE as it is the value set by befault on the per sta nonpeer_pm field. As we want no power save by default, (as expressed with the per sta ini values), lets init it to the expected default value of NL80211_MESH_POWER_ACTIVE. Also please note that we cannot change the default value from userspace prior to establishing a link as using NL80211_CMD_SET_MESH_CONFIG will not work before NL80211_CMD_JOIN_MESH has been issued. So too late for our initial scan.
