*How long to wait the fragments to receive*

Type: ``int``

Help
====

.. code-block:: none

    How long to wait for IPv6 fragment to arrive before the reassembly
    will timeout. RFC 2460 chapter 4.5 tells to wait for 60 seconds but
    this might be too long in memory constrained devices. This value
    is in seconds.
