Subject: [PATCH 1/2] fixup! net: switchdev: propagate extack to port
attributes
J721e, J7200 and AM64 have multi port switches which can work in multi
mac mode and in switch mode. Add documentation explaining how to use
different modes.

This series adds switchdev support for AM65 CPSW NUSS driver to support
multi port CPSW present on J721e and AM64 SoCs.
It adds devlink hook to switch b/w switch mode and multi mac mode.
v2:
Rebased on latest net-next
Update patch 1/4 with rationale for using devlink
Vignesh Raghavendra (4
- SWITCHDEV_ATTR_ID_PORT_STP_STATE
- SWITCHDEV_OBJ_ID_PORT_VLAN
- SWITCHDEV_OBJ_ID_PORT_MDB
- SWITCHDEV_OBJ_ID_HOST_MDB
Hence AM65 CPSW switchdev driver supports:
- FDB offloading
- MDB offloading
- VLAN filtering and offloading
- STP
Signed-off-by: Vignesh Raghavendra
reconfiguration, therefore is easier to be made as part of mode change
devlink hooks. It also allows to keep user interface similar to what
was implemented for the previous generation of TI CPSW IP
(on AM33/AM43/AM57 SoCs).
