[f-nsp] MLX with "route-only" port is forwarding VLAN1 BPDUs?

All right, I've tested this and now the MLX seems to generate VLAN666
BPDUs by itself on this port. At least I can see that the "BPDU Config
tx" counter is still rising.

So I can stop flooding VLAN1 BPDUs from other ports but now we have new
VLAN666 BPDUs on that port transmitted.
