From 2584fbc3a61897de5eddd56b39a4fa9cd074eca2 Mon Sep 17 00:00:00 2001 From: Roger So Date: Tue, 31 Jul 2007 23:52:42 +0200 Subject: [PATCH] r8169: PHY power-on fix Fix extracted from Realtek's driver (8.002.00/20070713) for the PHY attached to 8111/8168b chipsets. The check against mac_version is just usual paranoia during the bugfix period of the kernel cycle. -- FR Tested on Asus M2A-VM motherboard by Roger So. No regression on my Asrock 945G DVI either (built-in 8168 + 2x8169).
