Description of Problem:

DHCP sets the source-IP address to 0.0.0.0 on DHCPDISCOVER messages. Same
happens when doing "Duplicate address detection  mode  (DAD)" (see '-D' option
at 'man 8 arping').

When arpwatch sees such packages, it creates a 'arpwatch: bogon 0.0.0.0 <mac>'
message.


Version-Release number of selected component (if applicable):

arpwatch-2.1a11-16


How Reproducible:

100%


Steps to Reproduce:
1.  run arpwatch
2a. on a DHCP enabled machine release the lease and restart the machine, OR
2b. run 'arping -D <IP>'
3.  watch /var/log/messages


Actual Results:

something like.
| ... arpwatch: bogon 0.0.0.0 0:2:b3:9a:9f:c4


Expected Results:

no such message
