Bridging two vlans on a single interface don't work ( kernel2.6.15, tg3 driver for Broadcom NetXtreme BCM5705M_2 )

Dear List,
I am experiencing problems bridging two vlans on a linux box running debian.

I have a single interface (eth0,Broadcom NetXtreme BCM5705M_2 with tg3 
module).

This interface has a trunk to a catalyst switch.

 
I've created two virtual interface with vconfig:

vconfig add eth0 608
vconfig add eth0 609

At this point all is fully functional, I am able to see traffic on those 
virtual interfaces and if I give them the ip stack I can use them.

Then I decided two bridge the two virtual interfaces.

So I created a bridge with brctl :

brctl addbr br0

and I've added those virtual interfaces to the bridge :

brctl addif br0 eth0.608
brctl addif br0 eth0.609

Last thing I enable all the interfaces :

ifconfig br0 up
ifconfig eth0.608 up
ifconfig eth0.609 up

The first thing I noticed is that I cannot see any traffic on br0 
interface and also on the virtual interfaces.

As far as I know the bridge code supports tagged packet but I am not 
able to see any traffic on the interfaces.

Moreover the tg3 module support natively vlan traffic.

This is what I see on both br0 and virtual interfaces after I add them 
to the bridge :

Any ideas ?
