FPE implementation for DWMAC4 and DWXGMAC differs only for: 1) Offset address of MAC_FPE_CTRL_STS and MTL_FPE_CTRL_STS 2) FPRQ(Frame Preemption Residue Queue) field in MAC_RxQ_Ctrl1 3) Bit offset of Frame Preemption Interrupt Enable Tested on DWMAC CORE 5.20a and DWXGMAC CORE 3.20a Changes in v3: 1. Drop stmmac_fpe_ops and refactor FPE functions to generic version to avoid function pointers 2. Drop the _SHIFT macro definitions Changes in v2: 1. Split patches to easily review 2. Use struct as function param to keep param list short 3.
