ARP behavior in FreeBSD vs Linux

[Motonori Shindo]

On FreeBSD (and I guess most Operating Systems as well), ARP reply is
sent back only when the target IP address in ARP request matches with
one of the IP addresses assigned to the interface through which the
ARP Request is received. In contrast, on Linux (by default), it
responds as long as the target IP address in ARP Request matches with
any "local" IP address on the system, which is not necessarily an IP
address assigned to the interface through which the ARP request is
received.

Is there any advantage/disadvantage in ARP implementation on FreeBSD
over that of Linux? Thanks.
