Is CARP implemented on -CURRENT (FreeBSD 10)?

I'm playing around with some test boxes in the office running -CURRENT;
testbox# uname -a
FreeBSD testbox.ai.net 10.0-CURRENT FreeBSD 10.0-CURRENT #0: Wed Jan 18 19:=
21:12 EST 2012     root@testbox.ai.net:/usr/obj/usr/src/sys/CARP  amd64

I can't seem to create a carp interface despite having compiled a kernel wi=
th "device      carp" in it. Attempts to create a carp interface fail;
# ifconfig carp create
ifconfig: SIOCIFCREATE2: Invalid argument

>From what I've read in the handbook entry on CARP (http://www.freebsd.org/d=
oc/handbook/carp.html), I should be able to either compile in the carp devi=
ce, as above, or load the if_carp.ko kern module. There doesn't appear to b=
e a if_carp.ko module in the -CURRENT source tree, however. Only the carp m=
odule itself;
# ls -ald /usr/src/sys/modules/*carp*
drwxr-xr-x  2 root  wheel  512 Dec 27 15:12 /usr/src/sys/modules/carp

Am I missing something completely obvious? Was the functionality of if_carp=
.ko rolled into another module?
