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 ==================== Signed-off-by: David S.
