I don't think this patch is suitable for stable branches. This patch is
part of a patch series that changes the lapb module from "establishing the
L2 connection only when needed by L3", to "establishing the L2 connection
automatically whenever we are able to". This is a behavioral change. It
should be seen as a new feature. It is not a bug fix.
