None. The Linux kernel bridge only supports 802.1D bridging / [R]STP,
but not 802.1Q bridging / MSTP kernel part.

You can add eth0 & eth1 to a bridge and put the VLANs on the bridge
(br0.2 / br0.4 / br0.5). That would be a .1D bridge, then.

Or, you can take a look at OpenVSwitch, no idea if it does .1Q/MSTP.
