Subject: [PATCH 2/3] leds: trigger: netdev: add additional specific link
|
|
duplex mode
|
|
|
|
Add additional modes for specific link duplex. Use ethtool APIs to get the
|
|
current link duplex and enable the LED accordingly. Under netdev event
|
|
handler the rtnl lock is already held and is not needed to be set to
|
|
access ethtool APIs.
|
|
|
|
This is especially useful for PHY and Switch that supports LEDs hw
|
|
control for specific link duplex.
|
|
|
|
Add additional modes:
|
|
- half_duplex: Turn on LED when link is half duplex
|
|
- full_duplex: Turn on LED when link is full duplex
