Bridge STP support on VLANs

[d_mito]

Hello,

There is not so much info about this on google, and all posts are old.
All saying that it's not supported.

Is there anything changed since freebsd 6.2, I'm running 2.0-RC3 ?
In web interface is't possible to say on which interface to run STP.
But in logs there is always an error about invalid argument….

ifconfig bridge0 stp em0_vlan20
unable to set bridge flags: Invalid argument

I bridged 2 vlans em0_vlan20 and em1_vlan20
each physical interface in connected to different catalyst.
catalyst connected between them by trunk

I'd like to make my pfsense box root bridge.
But catalysts just see it transparent.
