[dpdk-dev] [PATCH v1 08/13] net/mlx5: call meter detach only if DR is supported

[Ophir Munk <ophirmu@nvidia.com>]

From: Ophir Munk <ophirmu@mellanox.com>

Flow metering is supported only in direct rules (DR). Currently the APIs
of meter actions create and modify are under #ifdef
HAVE_MLX5_DR_CREATE_ACTION_FLOW_METER, while detaching the meter action
is executed unconditionally. This commit adds the same ifdef to API
mlx5_flow_meter_detach().
This commit avoids compilation failure of non-Linux operating systems
which do not support DR.
