Transaction Termination as a PCI-X Target

split completion as it has a dedicated buffer for split completions. It also retries a cycle
when the bus is locked. The Intel
on a retry.
All cycles that cross the bridge receive this termination, when they are not retried.
Any I/O transaction that would cross from PCI-X to either the Hub Interface or the peer
bridge are not decoded and results in a master abort to the PCI-X initiator.
Arbitration

accept as a return. The bridge rules of the specification already allow the PCI-X
interface to retry split completions when the bridge is temporarily full.
Therefore, the split transaction control registers are not used by the Intel
