    Subject[PATCH 4.9 12/59] net/mlx5: Mask destination mac value in ethtool steering rules
    Date
    4.9-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Maor Gottlieb <maorg@mellanox.com>


    [ Upstream commit 077b1e8069b9b74477b01d28f6b83774dc19a142 ]

    We need to mask the destination mac value with the destination mac
    mask when adding steering rule via ethtool.

    Fixes: 1174fce8d1410 ('net/mlx5e: Support l3/l4 flow type specs in ethtool flow steering')
