Subject: net: phy: broadcom: Configure LEDs on BCM54210E
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=388cb2d321dd0bc5b0dc6e7f8e96d6d0f2929736;p=u-boot.git

net: phy: broadcom: Configure LEDs on BCM54210E

Configure LEDs on BCM54210E so they would blink on activity
and indicate link speed. Without this the LEDs are always on
if cable is plugged in.
