If it were true, it would, as other people have said, be a bug. But
the simple techniques described for AntiSniff don't work against even
vaguely modern NetBSD; indeed, I discovered this myself recently when I
had to make a NetBSD machine respond to packets for its IP address but
not its MAC address (unusual circumstances) - I had to comment out a
few lines in the relevant Ethernet driver.
