PCI-X spec clarification

["Solomon, Gary" <gary.solomon@intel.com>]

> All,
> 
> In Section 2.10.5 (Requirements for Accepting Split Completions) of the
> PCI-X Addendum the first sentence states without any qualification....
> 
> "The requester is required to accept all Split Completions resulting from
> its own Split Requests."
> 
> The danger here is that if the rest of the section is not carefully
> parsed, PCI-X devices (e.g., host bridges, NICs, etc.,) could be designed
> in such a way as to be incompatible with retries or other legitimate
> disconnects that are allowable for PCI-X bridges that proxy transactions
> for simple devices up or downstream of them.
> 
> Any device that is not accepting of, or cannot properly handle being
> retried in response to its Split Completion transaction will not work with
> PCI-X bridges.
> 
> May be speaking the obvious here to the development community, but in any
> event, would rather be safe than sorry.
