I set a successful AP network with WPA-PSK (see conf and log attached).
As you can see on log, the message "Could not set station
48:45:20:3b:31:75 flags for kernel driver" appears too, but the
connection is OK.

I'm not sure what to tell you. Did you look into the GTK installation
failure? For WPA-PSK, there's 1 4-way handshake and the STA installs
1 PTK and 1 GTK. For WPA2-PSK for IBSS, there are 2 4-way handshakes
and the STA installs 1 PTK and 2 GTKs. If the peer's GTK isn't
installed, the STA won't be able to decrypt the peer's broadcast
frames. Do you have a sniff of the failure? What's failing? Does it
work if you use static IP addresses and static ARP entries?
