.. title:: NET_ARP_GRATUITOUS

.. option:: CONFIG_NET_ARP_GRATUITOUS

*Support gratuitous ARP requests/replies.*

Type: ``bool``

Help
====

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.
