SR-IOV VF NIC with bridge

Hello all,

I have a problem about SR-IOV.

I use Xen and SR-IOV NIC. Instead of using passthrough NIC, I want to use VF NIC for bridge like

------+ (eth0-PF) +------

|        (eth2-VF)        |

|               |              |

|     --+------+--------(br0)|

|       |                        |

|   (vif1.0)                   |

|   domU                    |

---------------------------------

In this case, outgoing traffic of domU is passed by vif1.0 --> br0 --> eth2.

The problem is eth0 of domU has different MAC address compared with eth2's. and the traffic of domU is not passed in eth2. My guess is that eth2(VF) drops ethernet frame which has different MAC address.

Is there any one how to solve this problem.

Thanks,
