      net: dsa: Provide CPU port statistics to master netdev · badf3ada
      Florian Fainelli authored
      This patch overloads the DSA master netdev, aka CPU Ethernet MAC to also
      include switch-side statistics, which is useful for debugging purposes,
      when the switch is not properly connected to the Ethernet MAC (duplex
      mismatch, (RG)MII electrical issues etc.).
      
      We accomplish this by retaining the original copy of the master netdev's
      ethtool_ops, and just overload the 3 operations we care about:
      get_sset_count, get_strings and get_ethtool_stats so as to intercept
      these calls and call into the original master_netdev ethtool_ops, plus
      our own.
      
      We take this approach as opposed to providing a set of DSA helper
      functions that would retrive the CPU port's statistics, because the
      entire purpose of DSA is to allow unmodified Ethernet MAC drivers to be
      used as CPU conduit interfaces, therefore, statistics overlay in such
      drivers would simply not scale.
      
      The new ethtool -S <iface> output would therefore look like this now:
      <iface> statistics
      p<2 digits cpu port number>_<switch MIB counter names>

      net: dsa: utilize of_find_net_device_by_node · 769a0202
      Florian Fainelli authored
      Using of_find_device_by_node() restricts the search to platform_device that
      match the specified device_node pointer. This is not even remotely true for
      network devices backed by a pci_device for instance.
      
      of_find_net_device_by_node() allows us to do a more thorough lookup to find the
      struct net_device corresponding to a particular device_node pointer.
      
      For symetry with the non-OF code path, we hold the net_device pointer in
      dsa_probe() just like what dev_to_net_dev() does when we call this
      function.

      net: dsa: Introduce dsa_is_port_initialized · d79d2107
      Guenter Roeck authored
      To avoid race conditions when using the ds->ports[] array,
      we need to check if the accessed port has been initialized.
      Introduce and use helper function dsa_is_port_initialized
      for that purpose and use it where needed.

      net: dsa: integrate with SWITCHDEV for HW bridging · b73adef6
      Florian Fainelli authored
      In order to support bridging offloads in DSA switch drivers, select
      NET_SWITCHDEV to get access to the port_stp_update and parent_get_id
      NDOs that we are required to implement.
      
      To facilitate the integratation at the DSA driver level, we implement 3
      types of operations:
      
      - port_join_bridge
      - port_leave_bridge
      - port_stp_update
      
      DSA will resolve which switch ports that are currently bridge port
      members as some Switch hardware/drivers need to know about that to limit
      the register programming to just the relevant registers (especially for
      slow MDIO buses).
      
      We also take care of setting the correct STP state when slave network
      devices are brought up/down while being bridge members.
      
      Finally, when a port is leaving the bridge, we make sure we set in
      BR_STATE_FORWARDING state, otherwise the bridge layer would leave it
      disabled as a result of having left the bridge.
