Hi This series adds multi-port support in mac-only mode (multi MAC mode) to TI AM65x CPSW driver in preparation for enabling support for multi-port devices, like Main CPSW0 on K3 J721E SoC or future CPSW3g on K3 AM64x SoC. The multi MAC mode is implemented by configuring every enabled port in "mac-only" mode (all ingress packets are sent only to the Host port and egress packets directed to target Ext. Port) and creating separate net_device for every enabled Ext. port. This series does not affect on existing CPSW2g one Ext. Port devices and xmit path changes are done only for multi-port devices by splitting xmit path for one-port and multi-port devices. Patches 1-3: Preparation patches to improve K3 CPSW configuration depending on DT Patches 4-5: Fix VLAN offload for multi MAC mode Patch 6: Fixes CPTS context lose issue during PM runtime transition Patch 7: Fixes TX csum offload for multi MAC mode Patches 8-9: add multi-port support to TI AM65x CPSW changes in v2: - patch 8: xmit path split for one-port and multi-port devices to avoid performance losses - patch 9: fixed the case when Port 1 is disabled - Patch 7: added fix for TX csum offload v1: https://lore.kernel.org/patchwork/cover/1315766/ Grygorii Strashko (9): net: ethernet: ti: am65-cpsw: move ale selection in pdata net: ethernet: ti: am65-cpsw: move free desc queue mode selection in pdata net: ethernet: ti: am65-cpsw: use cppi5_desc_is_tdcm() net: ethernet: ti: cpsw_ale: add cpsw_ale_vlan_del_modify() net: ethernet: ti: am65-cpsw: fix vlan offload for multi mac mode net: ethernet: ti: am65-cpsw: keep active if cpts enabled net: ethernet: ti: am65-cpsw: fix tx csum offload for multi mac mode net: ethernet: ti: am65-cpsw: prepare xmit/rx path for multi-port devices in mac-only mode net: ethernet: ti: am65-cpsw: add multi port support in mac-only mode drivers/net/ethernet/ti/am65-cpsw-nuss.c | 327 +++++++++++++++-------- drivers/net/ethernet/ti/am65-cpsw-nuss.h | 5 + drivers/net/ethernet/ti/cpsw_ale.c | 41 ++- drivers/net/ethernet/ti/cpsw_ale.h | 1 + drivers/net/ethernet/ti/cpsw_switchdev.c | 2 +- 5 files changed, 251 insertions(+), 125 deletions(-)
