[VLAN] Linux bridge+vlan+tagging

Hi Peter,
 
Sometimes we need a feature as requested. 
 
Check out http://ietfreport.isoc.org/ids/draft-sanjib-private-vlan-02.txt link. That is how it is implemented in a lot of switches.
 
Thanks,
Vishwas

Sure. Filter out unwanted traffic with ebtables.

But if the two PCs aren't supposed to see each other there's not much
point in having a bridge. Just use a different IP subnet for each
VLAN, make sure to disable forwarding on the Linux system and you're
all set.
