It seems that there is something wrong with "sent an invalid ICMP type"
mesage since the "[IPV4]: Be more verbose about invalid ICMPs sent to
broadcast" (~2003-06-23) patch.

# tcpdump -i eth0 -n icmp
tcpdump: listening on eth0
14:24:54.236365 > icmp: net unreachable (DF)

Before 2.4.22-pre2: sent an invalid ICMP error to a broadcast.

After 2.4.22-pre2: sent an invalid ICMP type 3, code 0 error to a broadcast: on eth0

uname -a:
Linux nannou 2.4.22-pre3 #1 Wed Jul 9 17:24:09 CEST 2003 i686 unknown
