X710 strips incoming vlan tag with SRIOV

$

Hi,

 

I have a VM using SRIOV interfaces based on X710 interfaces. This VM is connected to a physical router through the VF.

I would like to enable vlan tagging on the VM.

 

I can ping the physical router from the VM if I'm not using VLAN tagging on the interface.

When I add VLAN tagging on the interface (on the VM and on the physical router), the network connectivity is broken.

 

The physical router correctly receives the packets/frames from the VM.

The VM receives the packets/frames but without a VLAN tag, it seems that the VLAN tag has been stripped.

 

Here are some informations on my setup:

 

[root@SLI-SRV3 sysadmin]# ethtool -i eth1

driver: i40e

version: 1.6.27-k

firmware-version: 6.00 0x800034e6 18.3.6

expansion-rom-version:

bus-info: 0000:19:00.0

supports-statistics: yes

supports-test: yes

supports-eeprom-access: yes

supports-register-dump: yes

supports-priv-flags: yes

 

[root@SLI-SRV3 sysadmin]# ip link show eth1

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq portid 246e967eaabe state UP mode DEFAULT qlen 1000

    link/ether 24:6e:96:7e:aa:be brd ff:ff:ff:ff:ff:ff

    vf 0 MAC 52:54:00:5d:6a:60, spoof checking on, link-state auto, trust off

 

 

VIRSH network config:

    <interface type='hostdev' managed='yes'>

      <mac address='52:54:00:5d:6a:60'/>

      <driver name='vfio'/>

      <source>

        <address type='pci' domain='0x0000' bus='0x19' slot='0x02' function='0x0'/>

      </source>

      <alias name='hostdev0'/>

      <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>

    </interface>

 

 

Any idea about what could be the issue ?

 

Thanks,

 

Stephane
