From cd8ec06ac04f71077bfc89c1a7e55ba48cf4e911 Mon Sep 17 00:00:00 2001 From: Olga Shern Date: Wed, 13 Jul 2016 16:33:22 +0200 Subject: [PATCH] net/mlx5: work around gcc error RHEL 7.1's GCC for POWER8 reports the following error in one rte_memcpy() macro call by mlx5: error: array subscript is above array bounds [-Werror=array-bounds] It appears to be a GCC bug which can be worked around by making parentheses more explicit.
