Since a couple of days the kernel logs messages when 0.0.0.0 is detected
in a IP packet's source IP field:

	arp: zero IP addr from link address ...

Since this is quite normal behaviour for BOOTP/DHCP clients when they
first broadcast their discovery packets, I consider this logging (to the
console, per the default syslog.conf) as rather useless noise.

I suggest that at least the check be conjuncted with a test for a broadcast
destination address.
