[dpdk-stable] [PATCH 49/67] net/mlx5: fix flow director mask

[Yongseok Koh <yskoh@mellanox.com>]

From: Nélio Laranjeiro <nelio.laranjeiro@6wind.com>

[ upstream commit 3c0db1ab516498e96b42fa804a3cf14e0ccf7647 ]

During the transition to resurrect flow director on top of rte_flow, mask
handling was removed by mistake.

Fixes: 4c3e9bcdd52e ("net/mlx5: support flow director")
Cc: stable@dpdk.org
