From 144127ba566059f01c372f3031357bbf98e4d67c Mon Sep 17 00:00:00 2001 From: Alexander Kozyrev Date: Wed, 24 Mar 2021 15:04:35 +0000 Subject: [PATCH] net/mlx5: adjust modify field action endianness Masks that used to modify a packet field must be in a big endian format. Convert then to BE to ensure proper modification.
