#7373: Network connectivity lost when arp host address changes detected

I've seen this quite a few times and decided to open a ticket to track it.
gcc4 hybrid.
When there is an arp host on the network that changes it's mac address
(virtual machine? network stack bug?) all network connectivity is lost
until the arp host changes the mac address back.
example:
{{{
KERN: ARP host 1711150a updated with different hardware address
5c:26:0a:1a:2f:29.
KERN: ARP host 1711150a updated with different hardware address
00:50:56:76:f1:cb.
KERN: ARP host 1711150a updated with different hardware address
5c:26:0a:1a:2f:29.
}}}
* When the second message appears... network connectivity is lost (can't
ping gateway or anywhere external to my local IP)...
* when the third message appears (a few seconds later), network
connectivity is regained.
The MAC addresses and associated hosts are on the same subnet but not in
direct communication. I also noted a *large* number of hosts in the arp
table:
{{{
arp | wc -l
140
}}}
I know for a fact I have not spoken with 140 systems... my linux system on
the same network (which connects to many more hosts) only has 3-4 entries
at any given time (linux seems to drop arp hosts from the table when
connections are no longer present)
I am not sure if the ARP messages the cause of the problem or are the
result of another problem.
Priority at High as it blocks network connectivity and is commonly seen on
my large vlan'ed work subnet with many varying systems. Feel free to
reduce if deemed not a high priority issue.
