From 34215e7b2e7021740a562595218411e91d921d9f Mon Sep 17 00:00:00 2001 From: Francois Romieu Date: Fri, 13 Apr 2007 20:19:50 +0200 Subject: [PATCH] r8169: fix suspend/resume for down interface The PM hooks are no-op if the r8169 interface is down (i.e. !IFF_UP). However, as the chipset is enabled, the device will not work after a suspend/resume cycle. The patch always issue the required PCI suspend sequence and removes the module unload/reload workaround.
