+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.
