> The validity iteration count replaces the functionality of the owner bit in terms
> of indicating that a new CQE was written to buffer.
> On iteration=k on the CQ buffer, only entries with the iteration_count=k should
> be treated as new CQEs or mini CQE arrays.
> The validity iteration count is used when the Enhanced CQE compression is
> selected. Add this CQE field and the method to check it.
