From b08e1ed9cfcf789421b7eccdd941f3f681c0a4ab Mon Sep 17 00:00:00 2001 From: Emil Tantilov Date: Fri, 26 Jul 2013 07:34:54 +0000 Subject: [PATCH] ixgbe: zero out mailbox buffer on init This patch initializes the msgbuf array to 0 in order to avoid using random numbers from the memory as MAC address for the VF.
