Subject: [PATCH 5.4 043/111] net: dsa: lantiq_gswip: Dont use PHY auto polling
Date: Mon, 12 Apr 2021 10:40:21 +0200	[thread overview]
Message-ID: <20210412084005.686270019@linuxfoundation.org> (raw)
In-Reply-To: <20210412084004.200986670@linuxfoundation.org>

From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>

commit 3e9005be87777afc902b9f5497495898202d335d upstream.

PHY auto polling on the GSWIP hardware can be used so link changes
(speed, link up/down, etc.) can be detected automatically. Internally
GSWIP reads the PHY's registers for this functionality. Based on this
automatic detection GSWIP can also automatically re-configure it's port
settings. Unfortunately this auto polling (and configuration) mechanism
seems to cause various issues observed by different people on different
devices:
- FritzBox 7360v2: the two Gbit/s ports (connected to the two internal
  PHY11G instances) are working fine but the two Fast Ethernet ports
  (using an AR8030 RMII PHY) are completely dead (neither RX nor TX are
  received). It turns out that the AR8030 PHY sets the BMSR_ESTATEN bit
  as well as the ESTATUS_1000_TFULL and ESTATUS_1000_XFULL bits. This
  makes the PHY auto polling state machine (rightfully?) think that the
  established link speed (when the other side is Gbit/s capable) is
  1Gbit/s.
- None of the Ethernet ports on the Zyxel P-2812HNU-F1 (two are
  connected to the internal PHY11G GPHYs while the other three are
  external RGMII PHYs) are working. Neither RX nor TX traffic was
  observed. It is not clear which part of the PHY auto polling state-
  machine caused this.
- FritzBox 7412 (only one LAN port which is connected to one of the
  internal GPHYs running in PHY22F / Fast Ethernet mode) was seeing
  random disconnects (link down events could be seen). Sometimes all
  traffic would stop after such disconnect. It is not clear which part
  of the PHY auto polling state-machine cauased this.
- TP-Link TD-W9980 (two ports are connected to the internal GPHYs
  running in PHY11G / Gbit/s mode, the other two are external RGMII
  PHYs) was affected by similar issues as the FritzBox 7412 just without
  the "link down" events

Switch to software based configuration instead of PHY auto polling (and
letting the GSWIP hardware configure the ports automatically) for the
following link parameters:
- link up/down
- link speed
- full/half duplex
- flow control (RX / TX pause)

After a big round of manual testing by various people (who helped test
this on OpenWrt) it turns out that this fixes all reported issues.

Additionally it can be considered more future proof because any
"quirk" which is implemented for a PHY on the driver side can now be
used with the GSWIP hardware as well because Linux is in control of the
link parameters.

As a nice side-effect this also solves a problem where fixed-links were
not supported previously because we were relying on the PHY auto polling
mechanism, which cannot work for fixed-links as there's no PHY from
where it can read the registers. Configuring the link settings on the
GSWIP ports means that we now use the settings from device-tree also for
ports with fixed-links.

Fixes: 3e6fdeb28f4c33 ("net: dsa: lantiq_gswip: Let GSWIP automatically set the xMII clock")
