-Subject: [PATCH] arm64: dts: fsl: ls1028a: Disable eno3 and make swp5 the
- Felix CPU port
-
-This patch returns to the switch port setup from BSP 0.2, where the
-switch only had a single Ethernet connection to the CPU, via a tagging
-interface. Choose eno2 for this purpose, as it has higher bandwidth and
-also supports TSN offloads.
-
-The reason is that the switch is not able to do DSA tags on 2 CPU ports
-at the same time, and it is confusing to have so many ports with no
-clear indication which should be used for what (a "data" port and a
-"control" port).
-
-We don't revert to the BSP 0.2 RCW configuration, however. The ENETC
-port 3 is still enabled in the RCW, however it is not probed by Linux by
-default, since the large majority of use cases will not need it. For
-those that do (like originating 802.1CB traffic from the CPU), it can be
-enabled back by simply reverting this device tree change.
