Subject: Any way to configure a vlan interface to grab ONLY untagged frames?

It seems like running 'vconfig add IFACE 0' and using IFACE.0 would do this, but it doesn't actually seem to work that way.

If I capture on IFACE directly, I'd expect to get all traffic, including the tagged frames (with the tag intact). 
Looking to be able to bridge/capture/etc. and specifically only receive the untagged frames that haven't already been 
pulled out into a vlan specific interface.

Is there any way to accomplish this without using ebtables or other similar hacks?
