Hi David：

I think networking tree merge it is a better choice, as it mainly used to tell the NIC
drivers how to use the Relaxed Ordering Attribute, and later we need send patch to enable
RO for ixgbe driver base on this patch. But I am not sure whether Bjorn has some of his own
view. :)

Hi Bjorn:

Could you help review this patch or give some feedback ?

Thanks
Ding
