39f29f250a defconfig: Enable TDLS
Some distros (e.g., Debian and Arch) already build wpa_supplicant with
support for TDLS, and Fedora is about to enable this feature as well.
Set CONFIG_TDLS=y in wpa_supplicant default build configuration.

4294d221d3 D-Bus: Increase introspection buffer size
It was apparently possible to hit the 20000 octet limit in some cases,
so increase the limit to avoid process termination due to insufficient
room for preparing a response to Introspect calls.

79488da576 wolfssl: Do not hardcode include directory in wpa_supplicant build
This is not really appropriate for any kind of cross compilations and is

9ad3fe9343 dpp-nfc: Start handover server regardless of init-on-touch setting
The previous version was trying to force the handover roles based on the
--init-on-touch parameter on both sides. That is fine for some test
scenarios, but not appropriate for more normal use cases. Change this
design to enable handover server in all cases and only control starting
of the handover client based on --init-on-touch.

0c5edededa DPP: Fix config exchange with gas_rand_mac_addr
Do not use a random MAC address for the GAS exchange that is used as
part of the DPP protocol exchange since that would break DPP.
Configurator expects the same MAC address to be used for DPP
Authentication exchange and DPP Configuration exchange (GAS).

Since the DPP Authentication exchange has already used the MAC address
configured on the interface, use of a random address for the GAS
exchange would not provide any additional privacy protection. If a
random MAC address needs to be used for this type of an exchange, that
random address would need to be first configured on the interface before
starting DPP exchange.

This does not change GAS query behavior for any other use case, i.e.,
the gas_rand_mac_addr configuration continues to apply to all the
Interworking/Hotspot 2.0 uses.
