Subject: [PATCH net-next 0/6] net: Extend availability of PHY statistics

Hi all,

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

Florian Fainelli (6):
  net: Move PHY statistics code into PHY library helpers
  net: Allow network devices to have PHY statistics
  net: dsa: Pass stringset to ethtool operations
  net: dsa: Add helper function to obtain PHY device of a given port
  net: dsa: Allow providing PHY statistics from CPU port
  net: dsa: b53: Add support for reading PHY statistics
