This can be used to request Provision Discovery Request to be sent
for the purpose of joining a running group, e.g., to request the GO
to display a PIN that we can then use with p2p_connect join command.

Use the no-ACK send_mlme request to transmit Probe Response frames
in P2P Listen state. This reduces number of unnecessary transmissions
if the peer device has already moved away from the channel. It will most
likely go through Search state multiple times anyway, so even if the
response were to be lost, a new retry will happen at higher layer.

In some situations it might be benefical to send a unicast frame without
the need for getting it ACKed (probe responses for example). In order to
achieve this add a new noack parameter to the drivers send_mlme callback
that can be used to advise the driver to not wait for an ACK for this
frame.

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.

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.
In new Linux kernel versions (>=3.0), nl80211 adds scheduled scan
capability. In order to use this feature to its full extent, we need
to support it in the wpa_supplicant core, so that it can also be used
by other drivers.
This commit adds initial scheduled scan support operations and events.

This change is a first step in better supporting different driver
architectures for AP mode operations with nl80211. This commit in
itself does not add new functionality, but it makes it easier to add
new AP mode parameters to address needs of drivers that have more of
the MLME/SME in firmware or kernel.
Add support to wpa_supplicant for device-based GTK rekeying. In order to
support that, pass the KEK, KCK, and replay counter to the driver, and
handle rekey events that update the latter.

This should fix EAPOL reauthentication and rekeying timeout issues
with Intel clients when using WMM (e.g., with IEEE 802.11n). These
stations do not seem to be able to handle EAPOL data frames as
non-QoS Data frames after the initial setup.
This adds STA flags to hapd_send_eapol() driver op to allow
driver_nl80211.c to mark the EAPOL frames as QoS Data frame
when injecting it through the monitor interface.
This provides a means for the supplicant to directly request signal
quality metrics from the driver. This is useful, for example for
background scan algorithms that might ask desire this information
out-of-band with CQM events.

This adds partial callbacks and events to allow P2P management to be
implemented in a driver/firmware. This is not yet complete and is
very much subject to change in the future.
With the new kernel functionality coming to Linux to allow off-channel
TX, we can take advantage of that in the P2P code that currently uses
remain-on-channel. If a driver advertises support for it, it will be
asked to handle off-channel TX by itself.

WPS 2.0 mandates the AP to include WPS IE in (Re)Association Response
if the matching (Re)Association Request included WPS IE. Provide the
needed WPS IE information to the driver_ops API for drivers that
process association frames internally.
Note: This modifies the driver_ops API by adding a new argument to
set_ap_wps_ie().
For now, this applies to the test command that can be used to set
periodic NoA (p2p_set noa). The value are stored and periodic NoA
is enabled whenever there are no non-P2P STAs connected to the GO.
There is no absolute requirement for separating address allocation
into separate functions, so simplify the driver wrapper interface
to use just if_add and if_remove instead of adding the new
alloc_interface_addr() and release_interface_addr() functions.
if_add() can now indicate if the driver forced a different interface
name or address on the virtual interface.
wpa_supplicant can now be notified of suspend/resume events, e.g.,
from pm-action scripts. This allows wpa_supplicant to clear information
that may become invalid during a suspend operation.
Some drivers may need to use a specific ifname for the virtual
interface, so allow them to do this with a new parameter passed
to the alloc_interface_addr() handler.
This adds new commands and events for allowing off-channel Action
frame exchanges to be requested. This functionality is not yet used
and is only fully supported by driver_test.c at this point.
driver_nl80211.c has support for the remain-on-channel commands, but
the Action frame TX/RX part is still pending review for the kernel
code and as such, is not yet included here.
This adds placeholder code for allowing the virtual interfaces to be
pre-allocated a MAC address before the interface type is known with
drivers that do not handle interface type changes.
This gets rid of previously deprecated driver_ops handlers set_wpa,
set_drop_unencrypted, set_auth_alg, set_mode. The same functionality
can be achieved by using the init/deinit/associate handlers.
Clean up driver interface by merging hostapd and wpa_supplicant
specific set_beacon driver_ops into a single one. In addition,
merge set_beacon_int into to the same operation.
