Consider network topology as follows:

bond0 --- br0

vlan0 --- br1

bond0 serves for both br0 and vlan0, if a vlan tagged packet was sent
to br1 through bond0, bridge handling code is seeing the packet on bond0
and handing it off to my "legacy" bridge before vlan_tx_tag_present
and vlan_hwaccel_do_receive even haven't a chance to look at it.

Moving the vlan_tx_tag_present before bridge/macvlan handling code could
cure this.

Wouldn't this break "eth0 - br0 - br0.5"?

I think it would. One more reason to build a single interface stacking framework...
