Re: [dpdk-dev] [PATCH v4 2/2] common/mlx5: fix compilation flag on port query API

The title could be:
common/mlx5: fix compatibility with OFED port query API

07/07/2021 17:54, Viacheslav Ovsiienko:

The compilation flag HAVE_MLX5DV_DR_DEVX_PORT depends on presence
of mlx5dv_query_devx_port routine in rdma-core library.

The mlx5dv_query_devx_port routine exists only in OFED versions
of rdma-core library and is being planned to be removed and replaced
with Upstream compatible mlx5dv_query_port.

As mlx5dv_query_devx_port is being removed all the dependencies on
the HAVE_MLX5DV_DR_DEVX_PORT compilation flag are reconsidered.

May be interesting to record that the new compilation flag
HAVE_MLX5DV_DR_CREATE_DEST_IB_PORT is for OFED only,
and is required for compatibility with a future OFED version.
