net/mlx5: Added new parameters to reformat context
Adding new reformat context type (INSERT_HEADER) requires adding two new parameters to reformat context - reformat_param_0 and reformat_param_1. As defined by HW spec, these parameters have different meaning for different reformat context type. The first parameter (reformat_param_0) is not new to HW spec, but it wasn't used by any of the supported reformats. The second parameter (reformat_param_1) is new to the HW spec - it was added to allow supporting INSERT_HEADER. For NSERT_HEADER, reformat_param_0 indicates the header used to reference the location of the inserted header, and reformat_param_1 indicates the offset of the inserted header from the reference point defined by reformat_param_0.
