Subject: [PATCH v2 net-next 09/11] net: dsa: Move the phylink driver calls into port.c
In order to have a common handling of PHYLINK for the slave and non-user
ports, the DSA core glue logic (between PHYLINK and the driver) must use
an API that does not rely on a struct net_device.
These will also be called by the CPU-port-handling code in a further
patch.
