Subject: [PATCH] net: phy: bcm54xx: Encode link speed and activity
|
||
|
|
into LEDs
|
||
|
|
|
||
|
|
Previously the green and amber LEDs on this quad PHY were solid, to
|
||
|
|
indicate an encoding of the link speed (10/100/1000).
|
||
|
|
|
||
|
|
This keeps the LEDs always on just as before, but now they flash on
|
||
|
|
Rx/Tx activity.
