Subject: [PATCH net-next v7 0/8] net: stmmac: Refactor FPE as a separate module
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 v7:
1. Split stmmac_fpe_supported() changes into a separate patch
2. Unexport stmmac_fpe_send_mpacket() and make it static
3. Convert to netdev_get_num_tc()
4. Commit message update for the 3rd patch
V6:
https://patchwork.kernel.org/project/netdevbpf/list/?series=904502&state=%2A&archive=both
Changes in v6:
1. Introduce stmmac_fpe_supported() to improve compatibility
2. Remove redundant fpesel check
3. Remove redundant parameters of stmmac_fpe_configure()
V5:
https://patchwork.kernel.org/project/netdevbpf/list/?series=903628&state=%2A&archive=both
Changes in v5:
1. Fix build errors reported by kernel test robot:
https://lore.kernel.org/oe-kbuild-all/202410260025.sME33DwY-lkp@intel.com/
Changes in v4:
1. Update FPE IRQ handling
2. Check fpesel bit and stmmac_fpe_reg pointer to guarantee that driver
does not crash on a certain platform that FPE is to be implemented
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. Typo fixes in commit message and title
