Took a look at the freebsd cluster routers(running -current), we seem to
not have the carp info on lagg0, but on seperate vlans and we set the
vlan parent to lagg0 instead.

e.g.
lagg0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric
0 mtu 1500

options=4219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC,VLAN_HWTSO>
	ether 00:25:90:c2:85:32
	inet6 fe80::225:90ff:fec2:8532%lagg0 prefixlen 64 tentative scopeid
0x6 
	nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
	media: Ethernet autoselect
	status: active
	laggproto lacp lagghash l2,l3,l4
	laggport: em1 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
	laggport: em0 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
----
pflog0: flags=141<UP,RUNNING,PROMISC> metric 0 mtu 33160
pfsync0: flags=41<UP,RUNNING> metric 0 mtu 1500
	pfsync: syncdev: vlan33 syncpeer: 10.0.16.2 maxupd: 128 defer: off
----
vlan33: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
1500
	options=103<RXCSUM,TXCSUM,TSO4>
	ether 00:25:90:c2:85:32
	inet6 fe80::225:90ff:fec2:8532%vlan33 prefixlen 64 scopeid 0x9 
	inet 10.0.16.1 netmask 0xffffff00 broadcast 10.0.16.255 
	nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
	media: Ethernet autoselect
	status: active
	vlan: 33 parent interface: lagg0
