      net: ethernet: adi: Add ADIN1110 support · bc93e19d
      Alexandru Tachici authored 
      
The ADIN1110 is a low power single port 10BASE-T1L MAC-PHY
designed for industrial Ethernet applications. It integrates
an Ethernet PHY core with a MAC and all the associated analog
circuitry, input and output clock buffering.

ADIN1110 MAC-PHY encapsulates the ADIN1100 PHY. The PHY registers
can be accessed through the MDIO MAC registers.
We are registering an MDIO bus with custom read/write in order
to let the PHY to be discovered by the PAL. This will let
the ADIN1100 Linux driver to probe and take control of
the PHY.

The ADIN2111 is a low power, low complexity, two-Ethernet ports
switch with integrated 10BASE-T1L PHYs and one serial peripheral
interface (SPI) port.

The device is designed for industrial Ethernet applications using
low power constrained nodes and is compliant with the IEEE 802.3cg-2019
Ethernet standard for long reach 10 Mbps single pair Ethernet (SPE).
The switch supports various routing configurations between
the two Ethernet ports and the SPI host port providing a flexible
solution for line, daisy-chain, or ring network topologies.

The ADIN2111 supports cable reach of up to 1700 meters with ultra
low power consumption of 77 mW. The two PHY cores support the
1.0 V p-p operating mode and the 2.4 V p-p operating mode defined
in the IEEE 802.3cg standard.

The device integrates the switch, two Ethernet physical layer (PHY)
cores with a media access control (MAC) interface and all the
associated analog circuitry, and input and output clock buffering.

The device also includes internal buffer queues, the SPI and
subsystem registers, as well as the control logic to manage the reset
and clock control and hardware pin configuration.

Access to the PHYs is exposed via an internal MDIO bus. Writes/reads
can be performed by reading/writing to the ADIN2111 MDIO registers
via SPI.

On probe, for each port, a struct net_device is allocated and
registered. When both ports are added to the same bridge, the driver
will enable offloading of frame forwarding at the hardware level.

Driver offers STP support. Normal operation on forwarding state.
Allows only frames with the 802.1d DA to be passed to the host
when in any of the other states.

When both ports of ADIN2111 belong to the same SW bridge a maximum
of 12 FDB entries will offloaded by the hardware and are marked as such.

      treewide: replace '---help---' in Kconfig files with 'help' · a7f7f624
      Masahiro Yamada authored 
      Since commit 84af7a61

 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

      net: lantiq: Add Lantiq / Intel VRX200 Ethernet driver · fe1a5642
      Hauke Mehrtens authored 
      
This drives the PMAC between the GSWIP Switch and the CPU in the VRX200
SoC. This is currently only the very basic version of the Ethernet
driver.

When the DMA channel is activated we receive some packets which were
send to the SoC while it was still in U-Boot, these packets have the
wrong header. Resetting the IP cores did not work so we read out the
extra packets at the beginning and discard them.

This also adapts the clock code in sysctrl.c to use the default name of
the device node so that the driver gets the correct clock. sysctrl.c
should be replaced with a proper common clock driver later.

      net: change Exar/Neterion menu items to be alphabetical · d39db3b4
      Jon Mason authored 
      Neterion was standalone for several years, then acquired by Exar and
shutdown in 11 months without ever making any new Exar branded adapters.
Users would probably think of them as Neterion and not Exar (as there
have been no follow-on adapters and the vast majority ever sold were
under the Neterion name).

6c541b45

 ("net: ethernet: Sort Kconfig sourcing alphabetically")
sorted Kconfig sourcing based on directory names, but in a couple cases,
the menu item text is quite different from the directory name and is not
sorted correctly:

  drivers/net/ethernet/neterion/Kconfig    => "Exar devices"

To address that and clear up any confusion about the name, "Exar" was
changed to "Neterion (Exar)" and the relevant entries in the Makefile
and Kconfig were reordered to match the alphabetical organization.

      net: mscc: Add initial Ocelot switch support · a556c76a
      Alexandre Belloni authored 
      
Add a driver for Microsemi Ocelot Ethernet switch support.

This makes two modules:
mscc_ocelot_common handles all the common features that doesn't depend on
how the switch is integrated in the SoC. Currently, it handles offloading
bridging to the hardware. ocelot_io.c handles register accesses. This is
unfortunately needed because the register layout is packed and then depends
on the number of ports available on the switch. The register definition
files are automatically generated.

ocelot_board handles the switch integration on the SoC and on the board.

Frame injection and extraction to/from the CPU port is currently done using
register accesses which is quite slow. DMA is possible but the port is not
able to absorb the whole switch bandwidth.
