@ -124,6 +124,15 @@ The route for the referenced host points to a device upon which ARP is
required, but ARP was unable to allocate a routing table entry in which
to store the host's MAC address. This usually points to a misconfigured
routing table. It can also occur if the kernel cannot allocate memory.

.Em "arp: %d.%d.%d.%d is on if0 but got reply from %x:%x:%x:%x:%x:%x on if1" :
Physical connections exist to the same logical IP network on both if0 and if1.
It can also occur if an entry already exists in the ARP cache for the IP
address above, and the cable has been disconnected from if0, then reconnected
to if1.
This message can only be issued if the sysctl
.Dv net.link.ether.inet.log_arp_wrong_iface
is set to 1, which is the system's default behaviour.
