Forget to say, WCN7850 firmware support no more than 2 links in an MLO connection.
Currently host does not limit on the number of MLO links, that said, with above 3 patches
applied you will see all 3 links, and then a firmware crash is expected. Well... there
might be resulting kernel crash as well.
We have a series pending review which add limit on the number of links could be finally
established:
