From 17d7802b7772ddcf505581fe22cffcd2e8b5120e Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Fri, 19 May 2017 17:00:38 -0400 Subject: [PATCH] net: dsa: change scope of bridging code Now that the bridge join and leave functions only deal with a DSA port, change their scope from the DSA slave net_device to the DSA generic dsa_port.
