wifi: mac80211: mesh: init nonpeer_pm to active by default in mesh sdata
[ Upstream commit 6f6291f09a322c1c1578badac8072d049363f4e6 ]
With a ath9k device I can see that:
iw phy phy0 interface add mesh0 type mp
ip link set mesh0 up
iw dev mesh0 scan
Will start a scan with the Power Management bit set in the Frame Control Field.
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.
