-Subject: net: dsa: qca8k: add support for cpu port 6
-
-Currently CPU port is always hardcoded to port 0. This switch have 2 CPU
-ports. The original intention of this driver seems to be use the
-mac06_exchange bit to swap MAC0 with MAC6 in the strange configuration
-where device have connected only the CPU port 6. To skip the
-introduction of a new binding, rework the driver to address the
-secondary CPU port as primary and drop any reference of hardcoded port.
-With configuration of mac06 exchange, just skip the definition of port0
-and define the CPU port as a secondary. The driver will autoconfigure
-the switch to use that as the primary CPU port.
