07fecd3915 P2P: Remove Label config method
The P2P specification (3.1.4.3) disallows use of the Label configuration
method between two P2P devices. This was previously enforced at upper
level, but the obsolete code can be removed from wpa_supplicant. This
adds a bit more strict enforcement of the policy, but should not result
in practical differences since no known P2P implementation uses Label
config method.

c5db8e5170 P2P: Embed publically visible struct in peer info
This embeds some information about each P2P peer that will be publically
visible in a struct that is shared.

The dev_found notification function is also passed the new struct, which
requires some work for the driver-based P2P management.

9dac8c3eaf P2P: Limit the retransmission of GO Negotiation request to 120
If the peer you want to connect to is no longer available (does not
acknowledge frames) when wpa_supplicant sends GO Negotition Request
frames, retransmission of this frame is done until the associated
p2p_device  structure is removed on timeout. In that case, no signal
is emitted to  inform the GO Negotiation has failed.

When sending an Invitation Request frame, the same retransmission
mechanism is in place but limit the transmission to 100 and hitting
the limit generates an event.

This patch adds the same mechanism as the one in place for Invitation
Request, but with limit of 120 to match the existing wait_count for
for GO Negotiation.

91626c9fa7 P2P: Reselect operating channel preference based on best channels
When the peer does not include our initial preference in the Channel
List attribute during GO Negotiation, try to use the best channel of
the other band as the new preference instead of falling back to the
first channel in the intersection.

3f9285ff19 P2P: Delay send_action call if p2p_scan is in progress
In order to avoid confusing the driver with a new remain-on-channel
request, delay sending of a new Action frame if the driver indicates
Action frame RX diromg a scan.

0b8889d8e5 P2P: Do not stop Listen state if it is on correct channel
This is needed to optimize response to GO Negotiation Request frames.
The extra remain-on-channel cancel followed by new remain-on-channel for
the same channel takes too much time with some driver/firmware
designs for the response to go out quickly enough to avoid peer
timing out while waiting for our response.

0f66abd25b P2P: Add option for disabling intra BSS distribution
p2p_intra_bss configuration parameter can now be used to
disable/enable intra BSS distribution (bridging of frames between
the clients in a group).

ae3e342108 P2P: Add peer timeout into group formation 15 second timeout
This adds some more time for WPS provisioning step in case the peer
takes long time to start group interface operations.

fbe7027239 P2P: Provide local event on GO Neg Req rejection
If an authorized (p2p_connect used locally) GO Negotiation is
rejected when receiving GO Negotiation Request from the peer,
indicate the failure with a ctrl_interface P2P-GO-NEG-FAILURE
event. Previously, this event was only shown on the peer (i.e.,
the device receiving the GO Negotiation Response with non-zero
Status code).

e9a7ae41fa P2P: Use SSID from GO Negotiation to limit WPS provisioning step
In order to avoid picking incorrect SSID from old scan results, use
SSID from GO Negotiation to select the AP.

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.
