From 9520ed8fb8410dcb6babf751561a08f73ca03812 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Tue, 17 Jan 2017 20:41:39 -0500 Subject: [PATCH] net: dsa: use cpu_switch instead of ds[0] Now that the DSA Ethernet switches are true Linux devices, the CPU switch is not necessarily the first one. If its address is higher than the second switch on the same MDIO bus, its index will be 1, not 0. Avoid any confusion by using dst->cpu_switch instead of dst->ds[0].
