-Subject: [PATCH] bgmac: reset all 4 GMAC cores on init
-
-On a BCM4709 based device, I found that GMAC cores may be enabled at
-probe time, but only become usable after a full reset.
-Disable cores before re-enabling them to ensure that they are properly
-reset.

+This fixes Ethernet on D-Link DIR-885L with BCM47094 SoC. Felix reported

+I tested this for regressions on BCM4706, BCM4708A0 and BCM47081A0.
