[ovs-discuss] RSTP in VLAN

Hi
I've run into the situation where I need to receive/transmit VLAN-tagged RSTP frames.

I can not find any information on anyone ever doing that with OVS.
Any pointers on how to do that?

What I've tried so far:
A rule on the bridge in question:
ovs-ofctl add-flow br0 "table=0 priority=2000 dl_dst=01:80:c2:00:00:00/ff:ff:ff:ff:ff:ff actions=strip_vlan,NORMAL"
I expected at least the receive path to work with this.
However in syslog I still get
daemon.debug ovs-vswitchd: ovs|00010|rstp_sm(handler20)|DBG|br0, port 1: Bad STP or RSTP BPDU received
When a vlan tagged BPDU is received.

BR
Matthias
