> Subject: [dpdk-dev] [PATCH] common/mlx5: fix code arrangement in tag
> allocation
>
> Flow tag action is supported only when the driver has DR or DV support.
> The tag allocation is adjusted to the modes DV or DR.
>
> In case both DR and DV are not supported in the system, the driver
> handles static code for error report.
> This error code, wrongly, was compiled when DV is supported while in
> this case it cannot be accessed at all.
>
> Ignore the aforementioned static error code in case of DV by
> preprocessor commands rearrangement.
