net: socionext: different approach on DMA Current driver dynamically allocates an skb and maps it as DMA Rx buffer. In order to prepare for upcoming XDP changes, let's introduce a different allocation scheme. Buffers are allocated dynamically and mapped into hardware. During the Rx operation the driver uses build_skb() to produce the necessary buffers for the network stack. This change increases performance ~15% on 64b packets with smmu disabled and ~5% with smmu enabled Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: David S.
