*Support gratuitous ARP requests/replies.*

Type: ``bool``

Help

.. code-block:: none

    Gratuitous in this case means a ARP request or reply that is not
    normally needed according to the ARP specification but could be used
    in some cases. A gratuitous ARP request is a ARP request packet where
    the source and destination IP are both set to the IP of the machine
    issuing the packet and the destination MAC is the broadcast address
    ff:ff:ff:ff:ff:ff. Ordinarily, no reply packet will occur.
    A gratuitous ARP reply is a reply to which no request has been made.
