For this case, if CIDX is 0, the maximum PIDX update would be 6. In the example above, if traffic has already started and the CIDX is 4, the maximum PIDX update is 3. Available descriptors are always <ring size> - 2. At any time, the software should not update the PIDX to more than <ring size> - 2. For example, if queue size is 8, which ...
