From 450895d04ba13a96886eddfeddb11556ae8624f1 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Sun, 24 Mar 2019 00:18:46 +0200 Subject: 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. Signed-off-by: Vladimir Oltean Reviewed-by: Florian Fainelli Signed-off-by: David S.
