I reviewed this a while ago already.
It does not full fill one of the requirement.
Mainly it incurs yet additional DMA for timestamp that must be avoided.

Xuan's idea of combining in the used element is better than above, however it is not enough.
So lets progress on the new descriptor and completion format that addresses multiple of them.

This is the main reason to see all requirements in composite way and not the piece meal work of single feature.
