f78f278520 nl80211: Fix off-channel Action frame TX from GO with use_monitor
TX frequency gets lost when going through the monitor send MLME option
and this resulted in P2P operations like invitation from a GO failing
when the driver needs monitor socket, but would support offchannel TX.
Fix this by using frame_cmd path instead in case the monitor socket
would have been hit for action frame TX.

5d4c78fb1f nl80211: Reset nlmode to station on leaving IBSS
Previously, IBSS mode (NL80211_IFTYPE_ADHOC) was left in drv->nlmode
when leaving IBSS. This causes issues for send_mlme() handler for P2P
Probe Response transmission in Listen state. Fix this by clearing nlmode
back to NL80211_IFTYPE_STATION on leaving IBSS so that following P2P
operations can be executed correctly. Previously, this was fixed only
when the next authentication/association attempt in station mode
occured.

This adds ACS support to hostapd. Currently only survey-based
algorithm is available.

To use ACS you need to enable CONFIG_ACS=y in .config and use

60b13c2017 nl80211: Do not change type to station on P2P interfaces
It is possible that when trying to remove a dynamically added interface,
changing its type to station mode is not possible (since the kernel does
not support so in its interface combinations).

Since P2P interfaces are always dynamically added, avoid changing their
type to station in the deinit_ap() and deinit_p2p_client() nl80211
callbacks, assuming that the interface is about to be removed.

Stop AP command can be used by the driver as an event to indicate that
AP mode has stopped operation. WLAN driver may have encountered errors
that has forced the driver to report this event or concurrent operations
on virtual interfaces may have forced AP operation to be stopped. When

3f53c006c7 nl80211: Ignore disconnect event in case of locally generated request
Previously, there could be two disconnection events in core
wpa_supplicant when going through a case of wpa_supplicant-requested
disconnection with a driver that implements SME internally. This could
result in undesired behavior when a disconnection is followed by a new
connection attempt before the extra event has been received (e.g.,
during fast reassoc or WPS provisioning). Avoid such issues by ignoring
locally generated disconnect events after requesting cfg80211 to
disconnect.

This makes the previously used ignore_next_local_disconnect more
consistent by setting the variable within
wpa_driver_nl80211_disconnect() so that both callers get the same
behavior.

455299fb40 nl80211: Fix foreign address filtering for MLME frame events
Commit 97279d8d1a started filtering MLME
frame events based on Address 1 (destination) field. This works fine for
frames sent to us, but it did filter out some corner cases where we
actually want to process an event based on a frame sent by us. The main
such case is deauthentication or disassociation triggered by something
external to wpa_supplicant in the system. Fix this by accepting events
for frames where either Address 1 or 2 (transmitter) matches the
interface address.

In case that NL80211_PROTOCOL_FEATURE_SPLIT_WIPHY_DUMP is supported,
wiphy_info_handler() is called several times, where
NL80211_ATTR_MAX_REMAIN_ON_CHANNEL_DURATION is present only in one
