From 1bd68c04850b9e73f1c7022b9a8c38cd14ceb37d Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 3 Feb 2009 11:27:27 +0000 Subject: [PATCH] sky2: remove unneede workaround This workaround is not needed. It was inherited from sk98lin driver but only applies to an early development version of the chip that is not supported by sky2. The workaround required an unnecessary pci read which hurts performance Signed-off-by: Stephen Hemminger Signed-off-by: David S.
