net: dsa: rtl8366: Check VLAN ID and not ports

2019-10-07T16:58:23+00:00

[ Upstream commit e8521e53cca584ddf8ec4584d3c550a6c65f88c4 ]

There has been some confusion between the port number and
the VLAN ID in this driver. What we need to check for
validity is the VLAN ID, nothing else.

The current confusion came from assigning a few default
VLANs for default routing and we need to rewrite that
properly.

Instead of checking if the port number is a valid VLAN
ID, check the actual VLAN IDs passed in to the callback
one by one as expected.

Add a 1ms delay after reset deactivation. Otherwise the chip returns
bogus ID value. This is observed with 88E6390 (Peridot) chip.

net: dsa: sja1105: Fix broken fixed-link interfaces on user ports

2019-07-26T07:10:19+00:00

[ Upstream commit af7cd0366ee994e8b35985d407261dc0ed9dfb4d ]

PHYLIB and PHYLINK handle fixed-link interfaces differently. PHYLIB
wraps them in a software PHY ("pseudo fixed link") phydev construct such
that .adjust_link driver callbacks see an unified API. Whereas PHYLINK
simply creates a phylink_link_state structure and passes it to
.mac_config.

At the time the driver was introduced, DSA was using PHYLIB for the
CPU/cascade ports (the ones with no net devices) and PHYLINK for
everything else.

As explained below:

commit aab9c4067d2389d0adfc9c53806437df7b0fe3d5
Author: Florian Fainelli 
Date:   Thu May 10 13:17:36 2018 -0700

  net: dsa: Plug in PHYLINK support

  Drivers that utilize fixed links for user-facing ports (e.g: bcm_sf2)
  will need to implement phylink_mac_ops from now on to preserve
  functionality, since PHYLINK *does not* create a phy_device instance
  for fixed links.

In the above patch, DSA guards the .phylink_mac_config callback against
a NULL phydev pointer.  Therefore, .adjust_link is not called in case of
a fixed-link user port.

This patch fixes the situation by converting the driver from using
.adjust_link to .phylink_mac_config.  This can be done now in a unified
fashion for both slave and CPU/cascade ports because DSA now uses
PHYLINK for all ports.

net: dsa: microchip: Use gpiod_set_value_cansleep()

2019-06-26T20:22:29+00:00

Replace gpiod_set_value() with gpiod_set_value_cansleep(), as the switch
reset GPIO can be connected to e.g. I2C GPIO expander and it is perfectly
fine for the kernel to sleep for a bit in ksz_switch_register().

net: dsa: rtl8366: Fix up VLAN filtering

2019-06-15T20:40:30+00:00

We get this regression when using RTL8366RB as part of a bridge
with OpenWrt:

WARNING: CPU: 0 PID: 1347 at net/switchdev/switchdev.c:291
	 switchdev_port_attr_set_now+0x80/0xa4
lan0: Commit of attribute (id=7) failed.
(...)
realtek-smi switch lan0: failed to initialize vlan filtering on this port

This is because it is trying to disable VLAN filtering
on VLAN0, as we have forgot to add 1 to the port number
to get the right VLAN in rtl8366_vlan_filtering(): when
we initialize the VLAN we associate VLAN1 with port 0,
VLAN2 with port 1 etc, so we need to add 1 to the port
offset.
