[libvirt] Libvirt and QBG with VEB

I have a setup of virtual machines and wherein my virtual switch (OVS)
takes care of switching locally and it uses the network for talking to
VM's outside the server (like a VEB scenario I guess). I want Netlink
messages to be sent to LLDPAD. I understand that i had to modify the XML files and start the VM. But, i see from the XML that it supports only
VEPA, not VEB.
But, irrespective of VEB or VEPA, those VM information should be known to
the upstream switch through VDP. 802.1QBG seem to support this (both
VEPA and VEB)
But, for VEB, no net link messages are sent by libvirt. Why is that?
From the XML example, I see that:
<source dev=’eth2.20’ mode=’vepa’/>
tried different combinations by changing the interface type to bridge
and and trying Qbg as in below, I find that it doesn't send a Netlink
message to LLDPAD. There's no "mode=veb".
<parameters managerid='12' typeid='1193046' typeidversion='1' instanceid='09b00c53-8b5c-4eeb-8f00-d847aa05191b'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
How do i get this to work? Is this a limitation?
