Bhyve + carp on fbsd 10.1 / pfsense 2.2.1 not working!

[lunetics]

Hello,

Just made some test and came to the conclusion that the carp module / implementation somehow differes from the stock freebsd 10.1 implementation.

On a fresh freebsd 10.1 bhyve install i could make carp work:

$ uname -a
FreeBSD darkthrone 10.1-RELEASE-p9 FreeBSD 10.1-RELEASE-p9 #0: Tue Apr  7 01:09:46 UTC 2015    root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64

$/sbin/ifconfig vtnet0 vhid 1 advskew 100 pass test 192.168.1.210/24 state master alias
ifconfig: SIOCSVH: Invalid argument

$kldload carp

$/sbin/ifconfig vtnet0 vhid 1 advskew 100 pass test 192.168.1.210/24 state master alias
ifconfig: SIOCSVH: Invalid argument

$ ifconfig
…
media: Ethernet 10Gbase-T <full-duplex>status: active
carp: BACKUP vhid 1 advbase 1 advskew 100

---

In pfsense, the carp module is in the kernel, i'll get the first error (before loading carp module on a fresh install):

pfsense $/sbin/ifconfig vtnet0 vhid 1 advskew 100 pass test 192.168.1.210/24 state master alias
ifconfig: SIOCSVH: Invalid argument

is the stock carp module in the pfsense kernel? How come it doesn't work? Any Help?</full-duplex>
