Subject:  Vlan help

 
Hi,

I have a query,

I'm trying to configure port based vlan on fonera2201(5 ports) device.

I have enabled debugging in 802q/vlan.c( Kernel version 2.6.21.5 ), I
can see the interfaces created properly, but following message is
continuously displayed on console
 
vlan_skb_recv: ERROR: No net_device for VID: 103 on dev: eth0.1 [5]
vlan_skb_recv: skb: 8122f440 vlan_id: 67
vlan_skb_recv: ERROR: No net_device for VID: 103 on dev: eth0.1 [5]
vlan_skb_recv: skb: 8121eee0 vlan_id: 67
vlan_skb_recv: ERROR: No net_device for VID: 103 on dev: eth0.1 [5]
vlan_skb_recv: skb: 81115e20 vlan_id: 67
vlan_skb_recv: ERROR: No net_device for VID: 103 on dev: eth0.1 [5]
vlan_skb_recv: skb: 8106dbc0 vlan_id: 67

When user adds (vlan port numbers)details in /etc/config/network file,

How does switch driver gets invoked and configures the ports to
different vlans?

Sorry for my basic question, but I'm trying to understand the flow?

I'm unable to link, how does 8021q/vlan.c speak with either
dsa/mv88e6*(or any other switch driver to configure vlan ports.)

Thanks In Advance,
Sharad.
