[pve-devel] [PATCH] Virtual vlan tagging to bridge interface

[Alexandre DERUMIER]

>>QinQ vlan tagging.

can somebody explain me how qinq works exactly ?  (I'm reading cisco doc, but I'm not sure to understand how tagging is working exactly)

FYI we are using vlan tagging on bridges with Proxmox in production for over a year now, initially on 2.6.32 kernel and then on 3.10. We are using Intel gigabit and 10gigabit adapters. 


We posted the patches to the list a few months back, I believe these are very similar to Alexandre's patches. We have a more complex config in that we are also doing bonding and QinQ vlan tagging. 


Our setup looks like this: 


eth0,eth1,eth2,eth3---->bond0---->bond0.101---->vmbr0---->vmbr0.201<----tap interface 



That is using an outer tag of 101 and an inner tag of 201.

What do you mean by "don't work with any devices" ? 

My patch is to manage vlan tags on the bridge, not eth interface. 

eth0---->vmbr0<------tap interface 

vlan are tagged on tap interfaces plugged on vmbr0, with new "bridge" cmd. (like an access port on a cisco switch) 
and vlans are allowed to pass through eth0.(like a trunk port on cisco switch) 

So I think it should work with gre,ipsec,...(But I don't have tested it yet)

Thus, it’s a configuration issue and NOT a kernel issue. 

If alexandre’s patch don’t work with any devices it isn’t really interesting because it addressing other functionality and devices. I checked the patch and it use the same problematic part with eth*, wifi* and bond* check which fails with virtual devices like gre, ipsec,..
