From c9399a1c81f7c9811fbc1812421f1886ee101cf5 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 15 Sep 2013 09:39:19 +0000 Subject: [PATCH] brcm47xx: bgmac: fix internal switch initialization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some devices (BCM4749, BCM5357, BCM53572) have internal switch that requires initialization. We already have code for this, but because of the typo in code it was never working. This resulted in network not working for some routers and possibility of soft-bricking them. Use correct bit for switch initialization and fix typo in the define.
