yed, I see that too.


also found this:

"Bridge VLAN kernel/iproute2 incompatibility"
http://www.spinics.net/lists/linux-ethernet-bridging/msg04942.html

don't known if if could be related? a kernel patch has been submit in august.

some hardware see vlan1=novlan, but not sure it's working like that

mmm, what is vmbr1.3021 at vmbr1?
current proxmox implementation is ethx.302---vmbr1v302
(can you do a brctl show?)

But, with new vlan code, what we will do should be

ethx----vmbr1----tap

and configure virtual port on vmbr1, where tap is plugged, with vlan tag 302. (like a real switch)

The relevant commit says it's disabled by default. Strangely i don't see 
how to enable and use this from the commits message.

What do you mean by that?

mhm i could try that. So you mean instead of adding: 
vmbr1.3021 at vmbr1 
and 
vmbr1v3021 

just use vmbr1.3021 at vmbr1 and add the tap device to that one?

Yes it will use that one.
