Are you using the WLAN driver implementation from that kernel version or
updated version from Backports? If this is what comes with Linux 4.4,
there is a known issue in secure mesh and you would need to update the
kernel (or at least mac80211 using Backports) to make this work.

wpa_supplicant v2.6 has all the known mesh related issues fixed, but
this depends on the kernel (mac80211) having related issues addressed.
