Subject: [PATCH 2/4] net: phy: phy_device: Call into the PHY driver to set LED
|
|
offload
|
|
|
|
Linux LEDs can be requested to perform hardware accelerated blinking
|
|
to indicate link, RX, TX etc. Pass the rules for blinking to the PHY
|
|
driver, if it implements the ops needed to determine if a given
|
|
pattern can be offloaded, to offload it, and what the current offload
|
|
is. Additionally implement the op needed to get what device the LED is
|
|
for.
