+Subject: [PATCH] net: mscc: ocelot: split assignment of the cpu port into a
+ separate function
+
+Now that the places that configure routing destinations for the CPU port
+have been marked as such, allow callers to specify their own CPU port
+that is different than ocelot->num_phys_ports. A user will be the Felix
+DSA driver, where the CPU port is one of the physical ports (NPI mode).
