From 06b9cce42634a50f2840777a66553b02320db5ef Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 25 Feb 2022 11:22:23 +0200 Subject: net: dsa: pass extack to .port_bridge_join driver methods As FDB isolation cannot be enforced between VLAN-aware bridges in lack of hardware assistance like extra FID bits, it seems plausible that many DSA switches cannot do it. Therefore, they need to reject configurations with multiple VLAN-aware bridges from the two code paths that can transition towards that state: - joining a VLAN-aware bridge - toggling VLAN awareness on an existing bridge The .port_vlan_filtering method already propagates the netlink extack to the driver, let's propagate it from .port_bridge_join too, to make sure that the driver can use the same function for both.
