Where is CARP?

[Ashley Moran]

Hi

Am I missing something here?  I'm running FreeBSD 6.1/amd64 and I can't see 
any sign of CARP.  The man page is there but very little else:

$ sudo ifconfig carp0 create
ifconfig: SIOCIFCREATE: Invalid argument

$ sysctl -a | grep carp
net.inet.ip.same_prefix_carp_only: 0

I thought maybe it was a kernel option, but I can't see that either:
$ cd /usr/src/sys/amd64/conf && grep -i carp *
<NOTHING>

And I thought it might be a KLD:
$ cd /boot/kernel && ls *carp*
ls: *carp*: No such file or directory

Where is it hiding and how do I enable it?

Thanks
Ashley
