[PATCH net-next 00/12] Mellanox mlx5e XDP performance optimization

Hi Dave, This series provides some preformancee optimizations for mlx5e driver, especially for XDP TX flows. 1st patch is a simple change of rmb to dma_rmb in CQE fetch routine which shows a huge gain for both RX and TX packet rates. 2nd patch removes write combining logic from the driver TX
