Subject: [PATCH 252/454] lan78xx: Change LEDs to include 10Mb activity
|
|
|
|
|
|
|
|
|
|
The default LED modes put 1000Mb/activity on orange and 100Mb/activity
|
|
|
|
|
on green, but this leaves no indication for a 10Mb link. Change the
|
|
|
|
|
defaults to put 10Mb/100Mb/activity on green.
|
|
