From cd56a682326f9de4d77ee3afb99d13d25c478c08 Mon Sep 17 00:00:00 2001 From: Tobias Schramm Date: Sat, 23 Sep 2023 13:46:40 +0200 Subject: [PATCH] realtek: 5.15: rtl93xx: support 2500baseT and 5000baseT on USXGMII links The USXGMII implementation of Realtek switches can not only support 10GbE but also 2.5Gb and 5Gb on top of the usual data rates. Mark those as supported to allow them to be negotiated. This change has been tested on a ZyXEL XGS1250-12 with the following link partners: - NWA50AX Pro (2.5Gb) - RTL8152 USB NIC (2.5Gb) - AQC111 USB NIC (2.5Gb & 5Gb) Gbit and 10GbE has also been tested to still work fine with a variety of devices.
