Rely on build_skb in oreder to -allocate skb since the previous patch introduced buffer recycling using -the page_pool API. -This patch fixes even an issue in the original driver where dma buffers -are accessed before dma sync. -mvneta driver can run on not cache coherent devices so it is -necessary to sync DMA buffers before sending them to the device -in order to avoid memory corruptions. Running perf analysis we can -see a performance cost associated with this DMA-sync (anyway it is -already there in the original driver code). In follow up patches we -will add more logic to reduce DMA-sync as much as possible. - -Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> -Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> -Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> -Signed-off-by: David S.
