From b2b8913341119491a13d9b11b073dc3c4f907cb8 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Sat, 14 Aug 2021 02:04:22 +0300 Subject: net: dsa: tag_8021q: fix notifiers broadcast when they shouldn't, and vice versa During the development of the blamed patch, the "bool broadcast" argument of dsa_port_tag_8021q_vlan_{add,del} was originally called "bool local", and the meaning was the exact opposite. Due to a rookie mistake where the patch was modified at the last minute without retesting, the instances of dsa_port_tag_8021q_vlan_{add,del} are called with the wrong values. During setup and teardown, cross-chip notifiers should not be broadcast to all DSA trees, while during bridging, they should.
