From 0750701a3f74e831b6cb0ecc69be2f7eff94e819 Mon Sep 17 00:00:00 2001 From: Hannes Schmelzer Date: Wed, 22 Jun 2016 12:07:14 +0200 Subject: driver/net/fec: support fixed speed connection If MAC is directly connected to another MAC (like a switch for example) we don't need to probe for a phy, autoneogation and so on. We simply have to setup speed.
