I don't know about ebtables, but you can use the mac-vlan module to
do this.  Unfortunately, the mac-vlan patch is included in my larger
patch, so you'll either have to apply the whole thing (which shouldn't
hurt anything), or manually break out the mac-vlan related parts.

The big patch is here:

The user-space tool (mvl_config) is included in the latest vlan cvs snapshot:
