This the RFC v5 which introduces new CPSW switchdev based driver which is
operating in dual-emac mode by default, thus working as 2 individual
network interfaces. The Switch mode can be enabled by configuring devlink driver
parameter "switch_mode" to 1/true:
devlink dev param set platform/48484000.ethernet_switch \
name switch_mode value 1 cmode runtime

Just wondering about the migration plan.. Is this a replacement
driver or used in addition to the old driver?


Sry, I've missed you mail.

As it's pretty big change the idea is to keep both drivers at least for sometime.
Step 1: add new driver and enable it on one platform. Do announcement.
Step 2: switch all one-port and dual mac drivers to the new driver
Step 3: switch all other platform to cpsw switchdev and deprecate old driver.
