Subject: question about CONFIG_DPP2


wpa-2.9: We use CONFIG_DPP=y for our build. In looking through the supplicant code I see lots of instances of “#ifdef CONFIG_DPP2”. I have not found where CONFIG_DPP2 is defined. It is not in the supplicant or hostapd defconfig files. In fact the only place that I can find it defined is in ../tests/hwsim/example-hostapd.config. The README.DPP file does not mention it either.
What is the purpose of CONFIG_DPP2 ?
Does it need to be defined along with CONFIG_DPP ?
