Introduce page_pool support in virtio_net driver in order to recycle pages in RX buffer allocation and avoid reallocating through the page allocator. This applies to mergeable and small buffer modes.
The patch has been tested using the included selftests and additional edge case scripts covering device unbind/bind cycles, rapid interface open/close, traffic during close, ethtool stress with feature toggling, close with pending refill work, and data integrity verification.
