The size of the ARP table (in entries).

The maximum age of ARP table entries measured in deciseconds. The

default value of 120 corresponds to 20 minutes (BSD default).

bool "ARP address harvesting"
|

default n
|
|
---help---
|
|
Harvest IP/MAC address mappings from the ARP table from incoming
|
|
IP packets. If this option is selected, CONFIG_NET_ARTAB_SIZE
|
|
should be large enough to hold the hosts on the network.
|
|
|
|
This option is NOT recommended on busy networks with many remote
|
|
hosts. On such networks the ARP table will be full most of the
|
|
time and the MAC addresses that you want will get flushed from
|
|
the table often.

Enable logic to send ARP requests if the target IP address mapping
|

does not appear in the ARP table.

Send the ARP request this number of times before giving up and

deciding that the target IP address is non reachable.

config ARP_SEND_DELAYMSEC

int "ARP re-send delay"

default 20
|
|
---help---
|
|
Wait this number of milliseconds after sending the ARP request
|
|
before checking if the IP address mapping is present in the ARP
|
|
table. This time should be related to the maximum round trip time
|
|
on the network since it is basically the time from when an ARP
|
|
request is sent until the response is received.
