From 9e4b45f20c5aac786c728619e5ee746bffce1798 Mon Sep 17 00:00:00 2001 From: Clément Léger Date: Fri, 12 May 2023 09:27:10 +0200 Subject: net: dsa: rzn1-a5psw: enable management frames for CPU port MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, management frame were discarded before reaching the CPU port due to a misconfiguration of the MGMT_CONFIG register. Enable them by setting the correct value in this register in order to correctly receive management frame and handle STP.
