PCI-X Attributes

["Amit Shah" <Amit@dcmtech.com>]

Hi PCI-X Experts,

In a "PCI to PCI-X" Bridge where the transaction(originating at PCI) is getting converted from PCI to PCI-X, the PCI-X master makes his own attributes and drives them on the bus.

But for a PCI-X to PCI-X Bridge, when the transaction(originating on PCI-X Primary) get initiated on the PCI-X Secondary, can the Bridge drive his own attributes for that transaction, or should he drive the original attributes of the initiator. 

If the bridge drives his own attributes on Secondary, then the decoding of the split completion transaction on secondary would be much simpler.

Help Needed !!
