It will not be pulled in mainline because compilation fails on 32-bit:

drivers/net/mlx5/mlx5_rxtx.c: In function ‘mlx5_tx_burst’:
drivers/net/mlx5/mlx5_rxtx.c:523:10: error:
right shift count >= width of type [-Werror=shift-count-overflow]
     addr >> 32,
          ^~

Please Ferruh, remove the series from next-net.
