2024-08-16net: ethernet: mtk_eth_soc: Use ipv6_addr_{cpu_to_be32,be32_to_cpu} helpersSimon Horman
Use ipv6_addr_cpu_to_be32 and ipv6_addr_be32_to_cpu helpers to convert address, rather than open coding the conversion. No functional change intended. Compile tested only.

2023-07-19net: ethernet: mtk_eth_soc: always mtk_get_ib1_pkt_typeDaniel Golle
entries and bind debugfs files would display wrong data on NETSYS_V2 and later because instead of using mtk_get_ib1_pkt_type the driver would use MTK_FOE_IB1_PACKET_TYPE which corresponds to NETSYS_V1(.x) SoCs. Use mtk_get_ib1_pkt_type so entries and bind records display correctly.

2023-03-20net: ethernet: mtk_eth_soc: ppe: add support for flow accountingDaniel Golle
The PPE units found in MT7622 and newer support packet and byte accounting of hw-offloaded flows. Add support for reading those counters as found in MediaTek's SDK[1].

2021-03-24net: ethernet: mtk_eth_soc: add support for initializing the PPEFelix Fietkau
The PPE (packet processing engine) is used to offload NAT/routed or even bridged flows. This patch brings up the PPE and uses it to get a packet hash. It also contains some functionality that will be used to bring up flow offloading.
