7cfc4ac319 P2P: Add support for automatic channel selection at GO
The driver wrapper may now indicate the preferred channel (e.g., based
on scan results) on both 2.4 GHz and 5 GHz bands (and an overall best
frequency). When setting up a GO, this preference information is used
to select the operating channel if configuration does not include
hardcoded channel. Similarly, this information can be used during
GO Negotiation to indicate preference for a specific channel based
on current channel conditions.

p2p_group_add command can now use special values (freq=2 and freq=5)
to indicate that the GO is to be started on the specified band.

c973f3868a P2P: Remove P2P group on driver resource becoming unavailable
Add a new driver event, EVENT_INTERFACE_UNAVAILABLE, for indicating
that the driver is not able to continue operating the virtual
interface in its current mode anymore, e.g., due to operating
channel for GO interface forced to a DFS channel by another virtual
interface.

When this happens for a P2P group interface, the P2P group will
be terminated and P2P-GROUP-REMOVED event shows the reason for
this as follows:
P2P-GROUP-REMOVED wlan0 GO reason=UNAVAILABLE

93b7ddd032 P2P: Skip GO Neg Conf ack failure workaround of send failures
The workaround to ignore no ctrl::ack received for GO Negotiation
Confirmation frame was only supposed to be used when the frame was
actually transmitted and just the ack was not received. However, due
to the way the driver failure on transmitting the frame were reported,
this ended up getting applied for all failures in sending the GO
Negotiation Confirmation frame.

Improve this by providing a mechanism to indicate whether send_action
operations fail locally before the frame was actually transmitted or
because of not receiving ack frame after having transmitted the frame.

b5c9da8db3 P2P: Add mechanism for updating P2P channel list based on driver events
This allows P2P channel list to be updated whenever the driver changes
its list of allowed channels, e.g., based on country code from scan
results.

b73bf0a74b P2P: Stop connection attempt on PBC session overlap
The overlap condition cannot disappear before group formation timeout
hits, so there is no point in continuing in this case and failure can
be indicated immediately.

3dfda83d9c P2P: Add Device Password ID to GO Neg Request RX event
This event indicates the Device Password ID that the peer tried
to use in GO Negotiation. For example:
P2P-GO-NEG-REQUEST 02:40:61:c2:f3:b7 dev_passwd_id=4

72044390f3 P2P: Add support for cross connection
If enabled, cross connection allows GO to forward IPv4 packets
using masquerading NAT from the P2P clients in the group to an
uplink WLAN connection. This is disabled by default and can be
enabled with "wpa_cli p2p_set cross_connect 1" on the P2P device
interface.

aefb53bd5d P2P: Disable periodic NoA when non-P2P STA is connected
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.

4c08c0bd57 P2P: Include P2P IE in (Re)AssocReq to infra AP if it uses P2P IE
While this is not strictly speaking required by the P2P specification
for a not-P2P Managed Device, this can provide useful information for
the P2P manager AP and may be needed to pass certification tests.
