--- Comment #6 from Bruno Damour <bruno@ruomad.net> ---
on host ifconfig ixv1 or ixv2 or ixv3 reports

interface ixv1 does not exist
interface ixv2 does not exist
interface ixv3 does not exist


but I can jexec into the jails and the interfaces ixv1 or ixv2 are displayed by
ifconfig

NB If I try to use the network inside a jail (VF 1 or VF 2) it generates also 

ix0: invalid DM target from VF 1; reset VF

and then

ix0: quarantined VF 1 after 5 invalid DMA targets

so this happen as soon as there is traffic on the VF (VF 3 fails immediately
because it launches a VPN connection upon start)
