From fe59de38c58d3eedc025be61ff3055a41776bbd4 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Tue, 26 Aug 2008 04:25:05 -0700 Subject: igb: ethtool -d reads EICR which is incorrect as it is read on clear Ethtool -d is reading the EICR and ICR registers which is currently clearing these registers and masking off interrupts. To prevent this we read the EICS and ICS equivilents as they can be read without clearing or masking.
