ARP Spoofing Prevention Settings

The user can configure the spoofing prevention entry to prevent spoofing of MAC for the protected gateway. When an
entry is created, those ARP packets whose sender IP matches the gateway IP of an entry, but its source MAC field
does not match the gateway MAC of the entry will be dropped by the system.
