From 3dbdf96928dcdece134113c8ffa137f1a3b5dd88 Mon Sep 17 00:00:00 2001 From: Carolyn Wyborny Date: Wed, 12 Sep 2012 04:36:24 +0000 Subject: [PATCH] igb: Fix stats output on i210/i211 parts. Due to a hardware issue, on i210 and i211 parts, the TNCRS statistic provides an invalid value. This patch changes the update stats function to increment the stat only for non-i210/i211 parts.
