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.

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.

Only core revisions older than 4 use BGMAC_CMDCFG_SR_REV0. This mainly
fixes support for BCM4708A0KF SoCs with Ethernet core rev 5 (it means
only some devices as most of BCM4708A0KF-s got core rev 4).
This was tested for regressions on BCM47094 which doesn't seem to care
which bit gets used.
