From 8e064c3d366703b802f8cbf93aeee3c4fa316d5c Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Fri, 28 Nov 2025 09:06:20 +0100 Subject: net: dsa: b53: fix extracting VID from entry for BCM5325/65 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 9316012dd01952f75e37035360138ccc786ef727 ] BCM5325/65's Entry register uses the highest three bits for VALID/STATIC/AGE, so shifting by 53 only will add these to b53_arl_entry::vid. So make sure to mask the vid value as well, to not get invalid VIDs.
