From b4dfd8e92956b396d3438212bc9a0be6267b8b34 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= <zajec5@gmail.com> Date: Tue, 12 Apr 2016 13:30:45 +0200 Subject: [PATCH] bgmac: reset & enable Ethernet core before using it MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This fixes Ethernet on D-Link DIR-885L with BCM47094 SoC. Felix reported similar fix was needed for his BCM4709 device (Buffalo WXR-1900DHP?). I tested this for regressions on BCM4706, BCM4708A0 and BCM47081A0.
