From 165f4d1cb3d7a10c5bc8c0fdae63323354f5a225 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Mon, 16 Jul 2012 16:23:59 +0000 Subject: [PATCH] tg3: Fix the setting of the APE_HAS_NCSI flag The driver currently skips setting this flag if the VPD contains the firmware version string. We fix this by separating the probing of NCSI from the reading of the NCSI version string. The APE_HAS_NCSI flag is needed to properly read sensor data.
