[PATCH net-next v2 0/8] net: stmmac: Refactor FPE as a separate module

From: Furong Xu
Date: Fri Oct 18 2024 - 02:39:52 EST


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 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 v2:
1. Split patches to easily review
2. Use struct as function param to keep param list short
3. Typo fixes in commit message and title
