From a73bceb86df8f1e007b7f7691d7e38bb29601943 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Wed, 30 May 2018 03:00:07 +0200 Subject: [PATCH] staging: fsl-dpaa2: ethsw: 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.
