      ====================
      net: Extend availability of PHY statistics
      
      This patch series adds support for retrieving PHY statistics with DSA switches
      when the CPU port uses a PHY to PHY connection (as opposed to MAC to MAC).
      To get there a number of things are done:
      
      - first we move the code dealing with PHY statistics outside of net/core/ethtool.c
        and create helper functions since the same code will be reused
      - then we allow network device drivers to provide an ethtool_get_phy_stats callback
        when the standard PHY library helpers are not suitable
      - we update the DSA functions dealing with ethtool operations to get passed a
        stringset instead of assuming ETH_SS_STATS like they currently do
      - then we provide a set of standard helpers within DSA as a framework and add
        the plumbing to allow retrieving the PHY statistics of the CPU port(s)
      - finally plug support for retrieving such PHY statistics with the b53 driver
      
      Changes in v3:
      
      - retrict the b53 change to 539x and 531x5 series of switches
      - added a change to dsa_loop.c to help test the feature
      
      Changes in v2:
      
      - got actual testing when the DSA master network device has a PHY that
        already provides statistics (thanks Nikita!)
      
      - fixed the kbuild error reported when CONFIG_PHYLIB=n
      
      - removed the checking of ops which is redundant and not needed
      ====================

      net: dsa: loop: Hook PHY statistics · 96cbddcd
      Florian Fainelli 提交于
      We just return the same statistics through ethtool_get_stats() and
      ethtool_get_phy_stats() for simplicity since this is just a mock-up driver.

      net: dsa: b53: Add support for reading PHY statistics · c7d28c9d
      Florian Fainelli 提交于
      Allow the b53 driver to return PHY statistics when the CPU port used is
      different than 5, 7 or 8, because those are typically PHY-less on most
      devices. This is useful for debugging link problems between the switch
      and an external host when using a non standard CPU port number (e.g: 4).
