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. Cc: Felix Fietkau <nbd@xxxxxxxxxxx> Signed-off-by: Rafał Miłecki <zajec5@xxxxxxxxx> Signed-off-by: David S.
