ABI: sysfs-bus-mdio: add alternate What for mdio symbolsNot all sysfs nodes are shown under: /sys/bus/mdio_bus/devices/...They can also be at: /sys/class/mdio_bus/.../So, update the What: entries to allow both.Signed-off-by: Mauro Carvalho Chehab Link: https://lore.kernel.org/r/aa51f6c2d482b28a349ba67e2a3904564e67496b.1632750608.git.mchehab+huawei@kernel.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-mdio

080bb352 - net: phy: Maintain MDIO device and bus statistics

Thu, 16 Jan 2020 04:48:50 +0000

net: phy: Maintain MDIO device and bus statisticsWe maintain global statistics for an entire MDIO bus, as well as brokendown, per MDIO bus address statistics. Given that it is possible forMDIO devices such as switches to access MDIO bus addresses for whichthere is not a mdio_device instance created (therefore not a acorresponding device directory in sysfs either), we also maintainper-address statistics under the statistics folder. The layout lookslike this:/sys/class/mdio_bus/../statistics/ transfers errrors writes reads transfers_ errors_ writes_ reads_When a mdio_device instance is registered, a statistics/ folder iscreated with the tranfers, errors, writes and reads attributes whichpoint to the appropriate MDIO bus statistics structure.Statistics are 64-bit unsigned quantities and maintained through theu64_stats_sync.h helper functions.Signed-off-by: Florian Fainelli Tested-by: Andrew Lunn Reviewed-by: Andrew Lunn Signed-off-by: David S.

56277f40 - phylib: mdio: Add sysfs attribute for PHY identifiers.

Wed, 07 Nov 2012 06:20:34 +0000

phylib: mdio: Add sysfs attribute for PHY identifiers.This adds a phy_id sysfs attribute to MDIO devices, containing the32-bit PHY identifier reported by the device. This attribute canbe useful when debugging problems related to phy drivers. Otherenumerable buses already have similar attributes.Signed-off-by: Nick Bowler Signed-off-by: David S.
