From 7edebf9a6aac07e2ebb3901b60672293a7139ad0 Mon Sep 17 00:00:00 2001 From: Emil Tantilov Date: Sat, 27 Aug 2011 07:18:37 +0000 Subject: [PATCH] ixgbe: prevent link checks while resetting It some situations the driver sets __IXGBE_RESETTING and then __IXGBE_DOWN flags. It is possible a link check may sneak in between. This patch adds check for both flags. The idea is to reduce register reads while the PHY is resetting.
