|
|
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
|

|
|
This attribute contains the 32-bit PHY Identifier as reported
|

|
|
by the device during bus enumeration, encoded in hexadecimal.
|

|
|
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.
