From f5ef017e1195d0a8c69a82bf95fea9c776b93ff0 Mon Sep 17 00:00:00 2001 From: Sriharsha Basavapatna Date: Sun, 9 Oct 2016 09:58:50 +0530 Subject: [PATCH] be2net: NCSI FW section should be properly updated with ethtool for BE3 The driver has a check to ensure that NCSI FW section is updated only if the current FW version in the card supports it. This FW version check is done using memcmp() which obviously fails in some cases. Fix this by breaking up the version string into integer version components and comparing them.
