Carp caching routes to networks

[Tom Judge]

Hi,

I came across an issue in RELENG_6_2 today where carp seems to be 
caching the network routes when the device is created. To trigger the 
problem try the following:

ifconfig bce0 10.0.0.150/8
ifconfig carp0 create
ifconfig bce0 172.31.23.2/24
ifconfig carp0 172.31.23.1/32


The last line will give an error indicating that it can not assign the 
address, I cant get the exact error message at the moment as I dont have 
access to the machine.

I was just wondering if this was a known problem or if is should raise a PR?

Thanks

Tom
