Use a driver_ndis.c specific initialization function to fill in the
wpa_driver_ops information to make it easier to modify struct
wpa_driver_ops in the future. Being able to build driver_ndis.c
with MSVC was the only reason for having to maintain the same order
of function pointers in struct wpa_driver_ops and for having to
update driver_ndis.c for all changes in that structure.

This code has not been maintained for years and there is no plan on
doing so either in the future. The Qt4-based wpa_gui-qt4 version can be
used as a replacement for this older wpa_gui version.

wpa_supplicant_rsn_preauth_scan_results() needs to be called to
update RSN pre-authentication candidates. This cannot be done before
the wpa_supplicant_connect() call on the first association, but when
trying to figure out whether to roam, it is fine to do so for the
case when roaming is skipped.

In scan.c, merge a channel's noise value into the scan results. When
comparing scan results, compute the signal-to-noise ratio and use it
when available. Prefer a 5 GHz network if its SNR is really big (> 30)
or if its SNR is relatively close to the other network's.
The eloop timeout to stop TKIP countermeasures has to be canceled
on deinit path to avoid leaving bogus timeouts behind.

Converts from a string to a control request enum when input

Add a D-Bus signal for EAP SM requests. This signal is emitted on the
Interface object so that clients only have to listen to one object for
requests rather than to all network objects. This signal is analogous
to the socket control interface's CTRL-REQ- request.

Control requests will be extended for non-EAP uses later, so it makes
sense to have them be generic. Furthermore, having them defined as an
enum is easier for processing internally, and more generic for control
interfaces that may not use field names. The public ctrl_req_type /
field_name conversion function will be used later by the D-Bus control
interface too.

At least with driver_test.c, the BSS table may not include frequency
information. In such a case, we need to skip rate set matching during
BSS selection to avoid rejecting valid AP.

The interface may not yet have been set to P2P client mode immediately
after GO Negotiation when doing the scan before association request.
Consequently, the scan request in this state has to specify that the
specific P2P probe mode is used to disable IEEE 802.11b rates.

This function was used unconditionally if wpa_supplicant build
includes CONFIG_P2P=y. Adding a separate driver_ops for such use
is not really useful since the driver wrappers can do the same
internally. Remove this driver_ops and move matching functionality
into driver_nl80211.c which was the only driver wrapper using
this driver_ops callback.

This can be used to apply the no-CCK rule conditionally depending on
which frame is being sent. The no-CCK rule applies only for P2P
management frames while SA Query and FT use cases do not have similar
restrictions.

wpa_supplicant dbus objects are currently difficult to use with
GDBusProxy. This is because they do not follow the dbus standard in
emitting the PropertiesChanged signal on the standard D-Bus properties
interface, so GDBusProxy stores stale property values.
Fix this by raising PropertiesChanged on the standard interface.
For backwards compatibility, the existing custom PropertiesChanged
signals are not removed; I anticipate them being removed in a future
major release.

P2P Client did not show correct frequency in the control interface
event P2P_EVENT_GROUP_STARTED. Fix that by using the frequency from
the BSS table or association event.
This patch stops any on-going "p2p_find" on creating an Autonomous GO.
This is already taken care in case of invoking a persistent GO. GO as
such will be advertising via the beacons for other devices to discover.
So normally the GO doesn't need to do a p2p_find until and unless it
wants to invite a P2P Client. In case of Invite scenario, logically it
is better to do a explicit discover [via user intervention] after the GO
is created. This patch will help to reduce battery wastage [due to
p2p_find operations] in scenarios where user creates a GO and doesn't
initiate a connection.
Once PBC overlap detected when using dynamic group interfaces, the wpa_s
corresponding to P2P group interface is freed. This patch avoids
accessing the wpa_s data structure after it is freed. This fixes a
possible crash in P2P client role in such a case.
The persistent_reconnect configuration parameter was used to decide
whether to accept invitation to re-establish a persistent group.
However, this was not being advertised in the Group Capability bitmap.
Add the Persistent Reconnect bit based on this configuration to GO
Negotiation frames and Beacon/Probe Response frames from the GO.
Use capability information to decide whether to perform a given TDLS
operation internally or through mgmt-frame Tx.

Before commencing setup, add a new STA entry to the driver representing
the peer. Later during setup, update the STA entry using information
received from the peer.
Extend sta_add() callback for adding/modifying a TDLS peer entry and
connect it to the TDLS state machine. Implement this callback for the
nl80211 driver and send peer information to kernel.
Mark TDLS peer entries with a new flag and translate it to a
corresponding nl80211 flag in the nl80211 driver.
In addition, correct TDLS related documentation in the wpa_driver_ops
structure.

These driver_ops functions set_channel, set_ssid, set_bssid,
mlme_add_sta, and mlme_remove_sta were used with the user space
MLME implementation in wpa_supplicant. That was only for testing
purposes and was removed, but these driver_ops were forgotten.
Remove them now to remove confusing driver_ops definitions.

This avoids allocating global driver state for driver wrappers that
are built in but not used. This can save some resources and avoids
failures with driver_nl80211.c that is now initializing netlink
connections for nl80211 in global_init().
This code was used only with driver_test.c to allow MLME operations
in hostapd to be tested without having to use a real radio. There
are no plans on extending this to any other use than testing and
mac80211_hwsim has now obsoled the need for this type of testing.
As such, we can drop this code from wpa_supplicant to clean up the
implementation of unnecessary complexity.
This command allows an external program manage the BSS blacklist
and display its current contents.
Note: The blacklist is considered to be internal mechanism within
wpa_supplicant and changing it can have unexpected results.
