4.19-stable review patch.  If anyone has any objections, please let me know.

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

From: Or Gerlitz <ogerlitz@mellanox.com>

[ Upstream commit 83621b7df6a646e550fd3d36db2e301cf9a5096b ]

We get the match level (none, l2, l3, l4) while going over the match
dissectors of an offloaded tc rule. When doing this, the match level
enum and the not min inline enum values should be used, fix that.

This worked accidentally b/c both enums have the same numerical values.

Fixes: d708f902989b ('net/mlx5e: Get the required HW match level while parsing TC flow matches')
