From 729a464f9a58fc77bf4e8f527a7848c6153e4b75 Mon Sep 17 00:00:00 2001
From: Ray Kinsella <ray.kinsella@intel.com>
Date: Mon, 8 Aug 2016 19:41:59 +0100
Subject: [PATCH] drivers: reset packet_type before using buffer
Ensure the packet_type is reset before the buffer is used. This can cause packets to be mishandled in systems with more than one type of driver in use.
