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.
