Subject[PATCH 4.10 012/111] net/mlx5e: Use the proper UAPI values when offloading TC vlan actions
Date
4.10-stable review patch.  If anyone has any objections, please let me know.

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

From: Or Gerlitz <ogerlitz@mellanox.com>


[ Upstream commit 09c91ddf2cd33489c2c14edfef43ae38d412888e ]

Currently we use the non UAPI values and we miss erring on
the modify action which is not supported, fix that.

Fixes: 8b32580df1cb ('net/mlx5e: Add TC vlan action for SRIOV offloads')
