[dpdk-dev] [PATCH v3 27/34] net/mlx5: simplify sample attributes

[Suanming Mou <suanmingm@nvidia.com>]

Currently, the sample action resource already has ft_type to indicate
the action domain attribute, the extra flow attributes parameter can
be optimized.

This commit uses action resource ty_type as domain attribute instead of
the flow attribute.
