Hello,
I'm trying to set up a wifi direct group between my AC9260 wifi board
and a android tablet supporting WifiDirect.

I tried several configurations and I faced some issues.
Here follow the testing sequence. All the following command are sent
through wpa_cli:

> p2p_find
P2P-DEVICE-FOUND f2:ee:10:c2:ce:68 p2p_dev_addr=f2:ee:10:c2:ce:68
pri_dev_type=10-0050F204-5 name='[Tablet] Galaxy Tab S3'
config_methods=0x188 dev_capab=0x25 group_capab=0x0 vendor_elems=1
new=1

>p2p_connect f2:ee:10:c2:ce:68 pin 1234 go_intent=1
74493685

PIN is set on the tablet then, on my terminal I see:

P2P-GO-NEG-SUCCESS role=GO freq=5785 ht40=0 peer_dev=f2:ee:10:c2:ce:68
peer_iface=f2:ee:10:c2:4e:68 wps_method=Display
P2P-GROUP-FORMATION-FAILURE
P2P-GROUP-REMOVED p2p-wlan0-0 GO reason=FORMATION_FAILED

dmesg :

It looks like the module firmware got an error when trying to set the
module in AP in 5GHz. I know there could be some regulatory limitation
for IBSS in 5Ghz, but why this does not work for wifi direct.
Thanks for your time.
