wpa_supplicant mesh mode issue

wpa_supplicant mesh mode issue

[Matteo Grandi]

Hi all,

I'm trying to set-up a mesh network using wpa-supplicant (already did
using iw and works fine) because I would like to implement security.
I followed the guide
https://wireless.wiki.kernel.org/en/users/drivers/ath10k/mesh?s[]=mesh&s[]=point
but I bump into some issues:

- when I set the parameter user_mpm=1 in the wpa_supplicant.conf file,
I have the llid and plid both set to 0 and the mesh points aren't able
to ping each other.
- Setting the parameter user_mpm=0 the peers can ping each other.
- If I implement the security I fall back to the same llid/plid=0 issue.

So it seems thet have user_mpm=1 and/or security implementation allows
to build the mesh, but it's impossible to ping and transmit on it.
Using user_mpm=0 allows the proper work of the mesh but only id
security is NOT used.

Is it ok to have llid/plid=0 when security is implemented or user_mpm=1?
Is someone already had this issue?

I'll be grateful for every hint!
Here my configuration file and the station dump:
