i40e/i40evf: avoid atomics In the case where we have a page fully used by receive data, we need to release the page fully to the stack. Instead of calling get_page (which increments the page count) followed by free_page (which decrements the page count), just donate our reference to the stack. Although this donation is not tax deductible, it does allow us to avoid two very expensive atomic operations that reverse each other.
