[dpdk-dev] [PATCH] net/mlx5: fix vectorized mini-CQE prefetching

2020-07-22 Thread Alexander Kozyrev
There was an optimization work to prefetch all the CQEs before their invalidation. It allowed us to speed up the mini-CQE decompression process by preheating the cache in the vectorized Rx routine. Prefetching of the next mini-CQE, on the other hand, showed no difference in the performance on x86
