Shouldn't you do the same for mlx5_uar_init_secondary()?
Looks like a few more. E.g. mlx5_args(), mlx5_get_mtu() and mlx5_uar_init_primary().
What about ibv_query_port() and mlx5_flow_create_drop_queue()?
Thanks

Instead of changing sign, how about 'err = rte_errno;' ?
However, err looks redundant to me because mlx5_* funcs set rte_errno.
Here, err is used to set rte_errno at the end.
Thanks,
