[PATCH net-next v1 0/7] net: stmmac: refactor FPE for gmac4 and xgmac

[Furong Xu]

Refactor FPE implementation by moving common code for DWMAC4 and
DWXGMAC into a separate FPE module.

FPE implementation for DWMAC4 and DWXGMAC differs only for:
1) Offset address of MAC_FPE_CTRL_STS
2) FPRQ(Frame Preemption Residue Queue) field in MAC_RxQ_Ctrl1

Tested on DWMAC CORE 5.20a and DWXGMAC CORE 3.20a

Furong Xu (7):
  net: stmmac: xgmac: drop incomplete FPE implementation
  net: stmmac: gmac4: drop FPE implementation for refactoring
  net: stmmac: refactor Frame Preemption(FPE) implementation
  net: stmmac: gmac4: complete FPE support
  net: stmmac: xgmac: rename XGMAC_RQ to XGMAC_FPRQ
  net: stmmac: xgmac: complete FPE support
  net: stmmac: xgmac: enable Frame Preemption Interrupt by default
