The phy_id field only shows the PHY ID of the C22 device, and the C45 device did not store its PHY ID in this field. Add a new phy_mmd_group, and export the mmd<n>_device_id for the C45 device. These files are invisible to the C22 device.

device has had any "fixup" workaround running on it, encoded as
|
|
a boolean. This information is provided to help troubleshooting

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.

|
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.
