From 76dd9d2f2f32dd5bb720ba6a2a9904ce361d059f Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Thu, 5 Apr 2018 14:46:11 +0100 Subject: [PATCH] lan78xx: Move enabling of EEE into PHY init code Enable EEE mode as soon as possible after connecting to the PHY, and before phy_start. This avoids a second link negotiation, which speeds up booting and stops the interface failing to become ready.
