> DCB config
>
> Mask used for clearing PRTDCB_RETSTCC register in function
> i40e_dcb_hw_rx_ets_bw_config() is incorrect as there is used
> define I40E_PRTDCB_RETSTCC_ETSTC_SHIFT instead of define
> I40E_PRTDCB_RETSTCC_ETSTC_MASK.

> The PRTDCB_RETSTCC register is used to configure whether ETS
> or strict priority is used as TSA in Rx for particular TC.
>
> In practice it means that once the register is set to use ETS
> as TSA then it is not possible to switch back to strict priority
> without CoreR reset.

> Fix the value in the clearing mask.
