This series applies on top of "[PATCH] eal: define generic vector types" [1][2] Using built-in vector types forces compilers to consider SIMD instructions in specific places in order to improve performance on both IBM POWER8 and Intel architectures. For example, testpmd single-thread I/O forwarding packets per second performance is improved by 6% on Intel platforms.

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]

Please Ferruh, remove the series from next-net.
