From 3cc9f2573cdcbc6991aa2d1c8e04a4b9190487f8 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 13 Jun 2017 13:27:22 -0700 Subject: net: dsa: Introduce dsa_get_cpu_port() Introduce a helper function which will return a reference to the CPU port used in a dsa_switch_tree. Right now this is a singleton, but this will change once we introduce multi-CPU port support, so ease the transition by converting the affected code paths.
