From ebc227fd91f26406840543074c2e7a55700a5644 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 21 Nov 2018 20:21:17 +0900 Subject: [PATCH] ravb: Do not announce HDX as supported According to the data sheet the Ethernet-AVB hardware in R-Car Gen3 and R-Car Gen2 SoCs do not support half duplex operation. So update the driver to mark 100Mbit and 1Gbps HDX as unsupported.
