phydev::dev_flags contains a bitmask of configuration bits requested by the consumer of a PHY device (Ethernet MAC or switch) towards the PHY driver. Since these flags are often used for requesting LED or other type of configuration being able to quickly audit them without instrumenting the kernel is useful.

What: /sys/class/mdio_bus///attached_dev Date: May 2017 KernelVersion: 4.13 Contact: netdev@vger.kernel.org Description: Symbolic link to the network device this PHY device is attached to.
What: /sys/class/mdio_bus///phy_has_fixups Date: February 2014 KernelVersion: 3.15 Contact: netdev@vger.kernel.org Description: This attribute contains the boolean value whether a given PHY device has had any "fixup" workaround running on it, encoded as a boolean. This information is provided to help troubleshooting PHY configurations.
What: /sys/class/mdio_bus///phy_id Date: November 2012 KernelVersion: 3.8 Contact: netdev@vger.kernel.org Description: This attribute contains the 32-bit PHY Identifier as reported by the device during bus enumeration, encoded in hexadecimal. This ID is used to match the device with the appropriate driver.
What: /sys/class/mdio_bus///phy_interface Date: February 2014 KernelVersion: 3.15 Contact: netdev@vger.kernel.org Description: This attribute contains the PHY interface as configured by the Ethernet driver during bus enumeration, encoded in string. This interface mode is used to configure the Ethernet MAC with the appropriate mode for its data lines to the PHY hardware.
Possible values are:
<empty> (not available), mii, gmii, sgmii, tbi, rev-mii,
rmii, rgmii, rgmii-id, rgmii-rxid, rgmii-txid, rtbi, smii
xgmii, moca, qsgmii, trgmii, 1000base-x, 2500base-x, rxaui,
xaui, 10gbase-kr, unknown
What: /sys/class/mdio_bus///phy_standalone Date: May 2019 KernelVersion: 5.3 Contact: netdev@vger.kernel.org Description: Boolean value indicating whether the PHY device is used in standalone mode, without a net_device associated, by PHYLINK. Attribute created only when this is the case.
What: /sys/class/mdio_bus///phy_dev_flags Date: March 2021 KernelVersion: 5.13 Contact: netdev@vger.kernel.org Description: 32-bit hexadecimal number representing a bit mask of the configuration bits passed from the consumer of the PHY (Ethernet MAC, switch, etc.) to the PHY driver. The flags are only used internally by the kernel and their placement are not meant to be stable across kernel versions. This is intended for facilitating the debugging of PHY drivers.
