Lennert reported that the change is needed for his 8110SB based n2100 board to work. Signed-off-by: Francois Romieu commit 49b6956e9f7c60e8262a87187f1d03f8316e1faf Author: Francois Romieu Date: Thu Nov 2 00:10:16 2006 +0100 r8169: more magic during initialization of the hardware Mostly taken from Realtek's driver. It's a bit yucky but the original is even worse.
