From 36501efdfc3151567bedc408a05e4bb818082400 Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Fri, 29 May 2015 15:34:15 +0100 Subject: [PATCH] i40e: fix build with gcc 5.1 On Fedora 22, with GCC 5.1, errors are reported due to array accesses being potentially out of bounds. This commit fixes this by adding in an extra bounds check to the loop counter.
