[dpdk-dev] [PATCH v2 7/8] net/mlx4: align Tx descriptors number

2017-12-06 Thread Matan Azrad
Using power of 2 descriptors number makes the ring management easier and allows to use mask operation instead of wraparound conditions. Adjust Tx descriptor number to be power of 2 and change calculation to use mask accordingly. Signed-off-by: Matan Azrad --- drivers/net/mlx4/mlx4_rxtx.c | 28 +
