working version is from Archlinux package manager (version 2.5) kernel 4.4.1
non working from source on the hostap website (version 2.5 tar.gz)

your are right I was about to say on my first email that my interface is 
part of an openvswitch bridge.
I remember in the past I needed to patch to make it work but I don't 
need to do it anymore on the version on ArchLinux
Does that mean the version is built with some patches the source doesn't 
include?

Many thanks
