From da0efa8888ee268ff7db74389a5e4fc32ade457a Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Wed, 30 May 2018 02:59:26 +0200 Subject: [PATCH] dsa: port: Ignore bridge VLAN events A follow-up patch enables emitting VLAN notifications for the bridge CPU port in addition to the existing slave port notifications. These notifications have orig_dev set to the bridge in question. Because there's no specific support for these VLANs, just ignore the notifications to maintain the current behavior.
