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.

Disable the direct connection when a TDLS peer stops responding

When a driver does not implement the TDLS_TEARDOWN operation internally,
send an explicit TDLS link teardown frame to the driver.
Change all teardown calls to use these calling semantics.

Put glue code in place to propagate TDLS related driver capabilities to
the TDLS state machine.
If the driver doesn't support capabilities, assume TDLS is supported
internally.
When TDLS is explicitly not supported, disable all user facing TDLS
operations.

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.
IEEE Std 802.11-2007 7.3.2.2 demands that in order to join a BSS all
required basic rates have to be supported by the hardware.

The hardware feature data is required in several different places
throughout the code. Previously, the data was acquired and freed on
demand, but with this patch wpa_supplicant will keep a single copy
around at runtime for everyone to use.

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.

This offloads the station polling to driver wrappers, which may offload
it again to the driver. The hostap driver wrapper uses "real" data
frames while nl80211 uses null data frames.
Also add a specific event to indicate that a poll was successful for
future use with the nl80211 driver.
This can be used to display the current debugging level and to change
the log level during run time.

This is the first step in allowing SA Query mechanism in hostapd to be
used with drivers that implement authentication and association MLME/SME
(i.e., do not use ieee802_11.c).
New configuration parameters home_imsi and home_milenage can be used
to configure SIM/USIM simulator parameters for network selection based
on SIM/USIM credentials.
home_imsi=(MCC | MNC | '-' | rest of IMSI)
home_milenage=(Ki):(OPc):(SQN)
For example:
home_imsi=310026-000000000
home_milenage=90dca4eda45b53cf0f12d7c9c3bc6a89:cb9cccc4b9258e6dca4760379fb82581:000000000123
Add support for network selection for username/password credentials with
EAP-TTLS and EAP-PEAP. The new global configuration parameters
home_username, home_password, and home_ca_cert can be used to specify
credentials for network selection.
This adds the basic mechanism for running through network selection:
scan, ANQP fetch, network selection, and connection. Actual rules for
network selection and the creation of the network block are still
missing, but will be added in separate commits.
Add mechanism for using GAS/ANQP to query Interworking related
information from APs. The received information is stored in the BSS
table and can be viewed with ctrl_iface BSS command.
New ctrl_iface command ANQP_GET can be used to fetch ANQP elements from
a specific AP. Additional commands FETCH_ANQP and STOP_FETCH_ANQP can be
used to initiate and stop an iteration through all APs in the BSS table
that indicate support Interworking to fetch ANQP elements from them.
"hostapd_cli ess_disassoc (STA addr) (URL)" can now be used to send
an ESS Dissassociation Imminent notification to the STA. This event
is shown in wpa_supplicant ctrl_iface monitors (e.g., wpa_cli):
"WNM: ESS Disassociation Imminent - session_info_url=http://example.com/session/"
The new wpa_supplicant.conf file global parameters interworking and
hessid can be used to configure wpa_supplicant to include
Interworking element in Probe Request frames.
EVENT_WPS_BUTTON_PUSHED wpa_supplicant_event can now be used in
station mode driver_*.c to indicate that a push button has been
pushed. This will activate WPS PBC mode.
When initializing, the scheduled scan code was being called before
everything is ready. With normal scans, the first scan round is
delayed, so the initialization is finished by the time it really
starts.
Add a function that can be used to request a delayed scheduled scan.
The scan will only start after the specified time has elapsed. Call
this function instead of starting the scheduled scan directly during
driver initialization.
