From c8512be63bbf9216934ecd10e1f9e4f887076fc2 Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Mon, 15 Oct 2012 15:09:52 +0200 Subject: [PATCH] NFC: Keep connection less bound sockets alive when DEP link goes down When DEP goes down, bound cl sockets can be kept alive as there is no reason to kill a connection less server socket because the LLCP link went down.
