ABI: sysfs-bus-mdio: add alternate What for mdio symbols

2021-09-28T10:48:15Z

Not 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.

net: phy: Maintain MDIO device and bus statistics

2020-01-17T10:12:44Z

We maintain global statistics for an entire MDIO bus, as well as broken down, per MDIO bus address statistics. Given that it is possible for MDIO devices such as switches to access MDIO bus addresses for which there is not a mdio_device instance created (therefore not a a corresponding device directory in sysfs either), we also maintain per-address statistics under the statistics folder. The layout looks like this: /sys/class/mdio_bus/../statistics/ transfers errrors writes reads transfers_ errors_ writes_ reads_ When a mdio_device instance is registered, a statistics/ folder is created with the tranfers, errors, writes and reads attributes which point to the appropriate MDIO bus statistics structure. Statistics are 64-bit unsigned quantities and maintained through the u64_stats_sync.h helper functions.

Documentation: net-sysfs: Remove duplicate PHY device documentation

2019-05-29T00:26:44Z

Both sysfs-bus-mdio and sysfs-class-net-phydev contain the same duplication information. There is not currently any MDIO bus specific attribute, but there are PHY device (struct phy_device) specific attributes. Use the more precise description from sysfs-bus-mdio and carry that over to sysfs-class-net-phydev.

net: phy: expose phydev->has_fixups to sysfs

2014-02-13T00:08:49Z

Expose the PHY device has_fixups boolean as a sysfs property to help troubleshooting PHY configurations. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: expose PHY device interface mode

2014-02-13T00:08:20Z

Expose the PHY device interface mode through sysfs since this is an useful piece of information for knowing how the attached networking device will have configured its transmit/receive path. Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

phylib: mdio: Add sysfs attribute for PHY identifiers.

2012-11-09T21:38:15Z

This adds a phy_id sysfs attribute to MDIO devices, containing the 32-bit PHY identifier reported by the device. This attribute can be useful when debugging problems related to phy drivers. Other enumerable buses already have similar attributes. Signed-off-by: Nick Bowler Signed-off-by: David S. Miller
