[dpdk-stable] [PATCH 27/33] net/mlx5: split L3/L4 in flow director

[Shahaf Shuler]

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

[ backported from upstream commit ca42b8a8b74956d179a25c94ccb7f5a516013da0 ]

This will help to bring back the mask handler which was removed when this
feature was rewritten on top of rte_flow.
