+From d8b1597130d228bc7e2bafd0c8d097529018c833 Mon Sep 17 00:00:00 2001
+From: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
+Date: Wed, 29 Aug 2012 22:08:15 +0200
+Subject: net: switchlib: add framework for ethernet switch drivers
+
+Add a generic framework similar to phylib for ethernet switch
+drivers and devices. This is useful to share the init and
+setup code for switch devices across different boards.
