Subject: [PATCH net-next v5 00/13] dsa: Broadcom Starfighter 2 switch support

Hi all,

This patch series adds support for the Broadcom Starfighter 2 (Roboswitch
successor) using the existing DSA infrastructure. This integrated switch
is heavily used in Set Top Box, Cable gateways and DSL gateways products
from Broadcom, and to a larger extent the new ARM-based Wi-Fi routers although
slightly differently.

Changes in v5 are the introduction of ETH_P_XDSA as suggested by Alexander to
help capture applications see this is a multiplexed DSA approach now.

Changes in v4 are the introducing of an indirection level for DSA switch tag
protocols receive and transmit functions.

I intentionnaly did not address one comment from Alexander who suggested to
move port_names and port_dn in a separate structure since that involves
touching arch/arm/ and arch/blackfin/ code which I am not yet comfortable
doing.

Notable changes in v3 is the preliminary patch that reworks the skb->protocol
override helpers for non-Ethertype switch tags, based on feedback from
Alexander Duyck.

The biggest changes from v1 of this patch series are:

- use the new fixed PHY helpers
- improved the switch driver with more complete features (interrupts,
  (RG)MII configuration, memory arrays power down/up, port disabling/enable
  VLAN separation

Future work will focus on bringing the upstream driver in feature parity with
the current downstream driver, including:

- adding Wake-on-LAN support to the switch
- adding suspend/resume callbacks for S2/S3 Power Management modes
- extending the switch register interface to cover BCM5310X SoCs

Florian Fainelli (13):
  net: dsa: reduce number of protocol hooks
  net: phy: add generic UniMAC MDIO bus driver
  net: phy: provide stub for fixed_phy_set_link_update
  net: dsa: provide a switch device device tree node pointer
  net: dsa: retain a per-port device_node pointer
  net: dsa: allow for more complex PHY setups
  net: dsa: allow switches to work without tagging
  net: dsa: allow drivers to do link adjustment
  net: dsa: allow updating fixed PHY link information
  net: dsa: add Broadcom tag RX/TX handler
  net: dsa: add Broadcom SF2 switch driver
