> Subject: [PATCH] net/mlx5: fix the port match in sample flow
> 
> If there are an explicit port match and sample action in the same flow,
> mlx5 PMD pushes the explicit port match in the prefix subflow, and uses the
> tag item match in the suffix subflow.
> 
> The explicit port match was translated into source vport match so the sample
> suffix subflow lost this match after flow split.
> 
> This patch copies the explicit port match to the sample suffix subflow, and
> the latter gets the correct source vport value in the flow matcher.
