From 3723b56d6f73f7c8c3b521a80556f129830f6fb9 Mon Sep 17 00:00:00 2001 From: Philippe Schenker Date: Tue, 30 Jan 2024 09:34:19 +0100 Subject: [PATCH] net: dsa: Add KSZ8567 switch support This commit introduces support for the KSZ8567, a robust 7-port Ethernet switch. The KSZ8567 features two RGMII/MII/RMII interfaces, each capable of gigabit speeds, complemented by five 10/100 Mbps MAC/PHYs.
