The packets never reach the TAP device.

Here is an output of ip a l (vlan 3021):

Can you provide output of brctl show?

Sure:
# brctl show
bridge name     bridge id               STP enabled     interfaces
vmbr0           8000.00259084dea8       no              bond0
                                                         tap320i0
vmbr1           8000.00259084deaa       no              bond1
vmbr1v3021              8000.00259084deaa       no              tap320i1
                                                         vmbr1.3021

so let me see if I can understand this configuration.

           vmbr1v3021 (bridge)
            /          \
        tap320i1       vmbr1.3021 (vlan)
                           \
                           vmbr1 (bridge)
                              \
                             bond1
                                \
                              eth X


Is that right? Is this the setup that has the problem you are
describing?

Thanks

On the off chance that you are actually trying to configure vlan
filtering, can you give this patch a try (net-2.6 tree):

Author: Toshiaki Makita [off-list ref]
Date:   Tue Aug 20 17:10:18 2013 +0900

     bridge: Use the correct bit length for bitmap functions in the VLAN
code

I don't think it made it to stable yet.

I addd that patch and now the vlan stuff works at least on the host
node. But my tap devices still don't work.

I also tried to attach the tap device on top of a vlan attached to bond1
but then gvrp does not work anymore. The kernel announces gvrp once and
then does not answer the query packets from the switch.
