Don't you use special setup with bridge on top of another bridge ? (It was about gvrp support If I remember)



About vlan filtering
--------------------
>>could you send me: 
>>zgrep 'VLAN' /prof/config.gz 
 ???? what is this ?

and 

sysctl -a | grep bridge

net.bridge.bridge-nf-call-arptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-filter-pppoe-tagged = 0
net.bridge.bridge-nf-filter-vlan-tagged = 0
net.bridge.bridge-nf-pass-vlan-input-dev = 0




I really don't understand why vlan filtering doesn't work( but it's not the first time that bridge module is buggy).
I'll try to ask to the netdev mailing list.




about openvswitch
-----------------
I have done some tests with openvswitch, and it's work really fine. 
iperf show me 20Gb/s, I never reach more than 8gb/s with linux bridge.
vlan work out of the box. 



@Dietmar

about openvswitch, I would like to add support to be able to plug kvm tap interface into it.
(simple detection if vmbrX is a linux bridge or openvswitch through sysfs, and then use brctl or ovz-ctl command to plug tap interface).

So advanced users could use them if they want. (create openvswitch command line, no support from gui)





A the end, I would like to have a proper implementation of linux bridge vlan_filtering and openvswitch. 
(with same network architecture,1 bridge with vlan management, so both can be interchanged)

Hi, 

it just works for me with vanilla 3.10 and the additional patch. BUT 
without VLAN filtering i don't use it. 

could you send me: 
zgrep 'VLAN' /prof/config.gz 

and 

sysctl -a | grep bridge
