Same as before. You have two for a single IP address/netmask (255.255.255.255 and the local one). You have another per address/mask pair you add.
The application supplies a target broadcast address so there isnt any real problem - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
