Hi Lu,

Many thanks for your response. Again I have few more queries.
If VF unicast promiscuous mode is not supported then can't we implement a
Layer 2 bridging functionality using intel virtualization technologies? Or
Is there any other way, say tweeking some hardware registers or drivers,
which may help us in implementing Layer 2 bridging.
Also I would like to know, why intel does not support unicast promiscuos
mode? It could have been optional register settings and user should have
had a previleage to set or unset it. Besides, security reasons, is there
any other big reason why Intel does not support this?

Thanks,
Bharath Paulraj
