Subject: [dpdk-stable] [PATCH] net/mlx5: fix calculation of flow ID flag
Date: Wed, 10 Jan 2018 23:57:53 -0800 [thread overview]
Message-ID: <20180111075753.34391-1-yskoh@mellanox.com> (raw)
PKT_RX_FDIR_ID should be set only if flow_tag is neither non-zero nor
MLX5_FLOW_MARK_DEFAULT.
Fixes: 6cb559d67b83 ("net/mlx5: add vectorized Rx/Tx burst for x86")
Fixes: 570acdb1da8a ("net/mlx5: add vectorized Rx/Tx burst for ARM")
