you want to play with it.
-config ARPD
- bool "IP: ARP daemon support"
- ---help---
- The kernel maintains an internal cache which maps IP addresses to
- hardware addresses on the local network, so that Ethernet
- frames are sent to the proper address on the physical networking
- layer. Normally, kernel uses the ARP protocol to resolve these
- mappings.
-
- Saying Y here adds support to have an user space daemon to do this
- resolution instead. This is useful for implementing an alternate
- address resolution protocol (e.g. NHRP on mGRE tunnels) and also for
- testing purposes.
-
- If unsure, say N.
