Trouble enabling p2p networking on 8 gen NUCs

[RFoll1]

I have several NUCs of earlier generations, and I can enable p2p networking on them with wpa_supplicant (I use Arch Linux).

But on a gen 8 NUC (NUC8i3BEK) I get trouble. The messages from wpa_supplicant:

nl80211: Create interface iftype 10 (P2P_DEVICE)

Failed to create interface p2p-dev-wlp0s20f3: -22 (Invalid argument)

nl80211: Failed to create a P2P Device interface p2p-dev-wlp0s20f3

P2P: Failed to create P2P Device interface

I tried updating the BIOS, did not help.

I am running Arch Linux, so I suppose I have very recent drivers for the system.

The command 'iw list' show support for p2p:

    Supported interface modes:

         * IBSS

         * managed

         * AP

         * AP/VLAN

         * monitor

         * P2P-client

         * P2P-GO

         * P2P-device

I tried connman and got p2p working. And I noticed the interfaces were renamed by connman. wlp0s20f3 became wlan0.

So I read up on the naming scheme with udev, and added "net.ifnames=0" to the kernel options. Then I am able to get p2p working without connman as well.
