Intel 82599 ES SR-IOV vlan support

$

Hi,

Our topology is :

    Spirent <->Ubuntu 12.04 Server <-> our application  within VM where VF is directly attached.

 

on VF interface , created   vlan interface and spirent has also also vlan interface.

 

NIC : Intel 82599 ES

IXGBE Version : 3.15.1-k

IXGBEVF driver version :2.7.12

 

By default, VF is not receiving any packet , even ARP Packet.  After configuring vlan filtering from  VF, it gets packet  with stripped vlan tag.

 

There are couple of questions :

1. Is there any way to configure from VF, so PF doesn't filter any vlan , simply pass traffic to VF ? I checked Spec , it mentions about this and by default, it is enabled.

2. How to avoid stripping of vlan tag ? I  changed accrording to spec  but it  stopped receiving any vlan packet.

3. Even I tried to add all vlans(1 to 4094) , but it doesn't work. it looks like only fixed entries(most likely 8) can be added .

 

Please let me know how to fix this problem from VF side, can't change PF code.

Thx,

Atulya
