From 30adcc8fab3fa5aa569ea804b3ad469895294fb4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Fri, 14 Apr 2017 10:34:59 +0200 Subject: [PATCH] hw/net: add MII definitions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This adds comments on the Basic mode control and status registers bit definitions. It also adds a couple of bits for 1000BASE-T and the RealTek 8211E PHY for the FTGMAC100 model to use.
