- 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.
