Hello: This patch was applied to netdev/net.git (main) by Paolo Abeni [off-list ref]: On Thu, 19 Sep 2024 16:13:51 +0800 you wrote:
Currently, the virtio-net driver will perform a pre-dma-mapping for small or mergeable RX buffer. But for small packets, a mismatched address without VIRTNET_RX_PAD and xdp_headroom is used for unmapping. That will result in unsynchronized buffers when SWIOTLB is enabled, for example, when running as a TDX guest. [...]
