      ravb: fix byte order for TX descriptor tag field lower bits · e49b42fa
      由 Niklas Söderlund 提交于 
      The wrong helper is used to swap the bytes when adding the lower bits of
the TX descriptors tag field in the shared ds_tagl variable. The
variable contains the DS[11:0] field and then the TAG[3:0] bits.

The mistake was highlighted by the sparse warning:

ravb_main.c:1622:31:    left side has type restricted __le16
ravb_main.c:1622:31:    right side has type unsigned short

      ravb: fix shadowing of symbol 'stats' in ravb_get_ethtool_stats() · c94f2fc4
      由 Niklas Söderlund 提交于 
      Inside a loop in ravb_get_ethtool_stats() a variable 'stats' is declared
resulting in the argument also named 'stats' to be shadowed. Fix this
warning by renaming the unused argument 'stats' to 'estats'.

      net: dsa: realtek-smi: Add Realtek SMI driver · d8652956
      由 Linus Walleij 提交于 
      This adds a driver core for the Realtek SMI chips and a
subdriver for the RTL8366RB. I just added this chip simply
because it is all I can test.

The code is a massaged variant of the code that has been
sitting out-of-tree in OpenWRT for years in the absence of
a proper switch subsystem. This creates a DSA driver for it.
I have tried to credit the original authors wherever
possible.

The main changes I've done from the OpenWRT code:

- Added an IRQ chip inside the RTL8366RB switch to demux and
  handle the line state IRQs.

- Distributed the phy handling out to the PHY driver.

- Added some RTL8366RB code that was missing in the driver at
  the time, such as setting up "green ethernet" with a funny
  jam table and forcing MAC5 (the CPU port) into 1 GBit.

- Select jam table and add the default jam table from the
  vendor driver, also for ASIC "version 0" if need be.

- Do not store jam tables in the device tree, store them
  in the driver.

- Pick in the "initvals" jam tables from OpenWRT's driver
  and make those get selected per compatible for the
  whole system. It's apparently about electrical settings
  for this system and whatnot, not really configuration
  from device tree.

- Implemented LED control: beware of bugs because there are
  no LEDs on the device I am using!

We do not implement custom DSA tags. This is explained in
a comment in the driver as well: this "tagging protocol" is
not simply a few extra bytes tagged on to the ethernet
frame as DSA is used to. Instead, enabling the CPU tags
will make the switch start talking Realtek RRCP internally.
For example a simple ping will make this kind of packets
appear inside the switch:

0000   ff ff ff ff ff ff bc ae c5 6b a8 3d 88 99 a2 00
0010   08 06 00 01 08 00 06 04 00 01 bc ae c5 6b a8 3d
0020   a9 fe 01 01 00 00 00 00 00 00 a9 fe 01 02 00 00
0030   00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

As you can see a custom "8899" tagged packet using the
protocol 0xa2. Norm RRCP appears to always have this
protocol set to 0x01 according to OpenRRCP. You can also
see that this is not a ping packet at all, instead the
switch is starting to talk network management issues
with the CPU port.

So for now custom "tagging" is disabled.

This was tested on the D-Link DIR-685 with initramfs and
OpenWRT userspaces and works fine on all the LAN ports
(lan0 .. lan3). The WAN port is yet not working.

      net: phy: realtek: Support RTL8366RB variant · d8545825
      由 Linus Walleij 提交于 
      The RTL8366RB is an ASIC with five internal PHYs for
LAN0..LAN3 and WAN. The PHYs are spawn off the main
device so they can be handled in a distributed manner
by the Realtek PHY driver. All that is really needed
is the power save feature enablement and letting the
PHY driver core pick up the IRQ from the switch chip.

      r8169: power down chip in probe · 07df5bd8
      由 Heiner Kallweit 提交于 
      The removed code would be called in two situations:
1. interface is brought up never or >10s after driver load
2. after close()

Case 1 we can handle cleaner by ensuring chip is powered down when
leaving probe(). open() callback will power up the chip.

In case 2 we call rtl_pll_power_down() twice currently, from the
close() callback and 10s later when entering runtime-suspend.
This is avoided by this patch.
