Hello Arend,
Did you had the chance to look into this?
Thanks for the ping, but no not really. I just noticed the mac address
in the p2p-dev create request is the null address and I recall that is
handled, but I will need to look into that. I will get back to you if I
have done so. Feel free to ping again when it is taking to long ;-)
Now the error is only an issue if you intend to setup a P2P connection
with some other device. For running in station or AP mode you can ignore
this. So if you have any specific issue and suspect this to be causing
it, please elaborate on the specific issue you see.
Regards,
Arend

This has been reported before, but not been able to look into it. Diving
into firmware it seems that error can only occur if the mac address for the
p2pdev interface is already used. So if possible can you rebuild the driver
with the patch below applied and provide dmesg output and output of
'ifconfig -a'.

Arend
