Hi Yegor, 
To establish a baseline here, 
Can you try using the officially supported packages by TI (Version R8.7) ?
See release notes here : http://software-dl.ti.com/ecs/WiLink8/R8_7/exports/release_notes_R8_7.html
It was validated to work with open and secured modes, based on Kernel 4.4.8 and hostap 2.5+

The Firmware version you are using is supporting secured mesh, so no issues there.

You can also have a look in our build guides http://processors.wiki.ti.com/index.php/WL18xx_System_Build_Scripts
