Subject[PATCH 69/78] virtio: don't expose u16 in userspace api
Date
3.8.13.1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: stephen hemminger <stephen@networkplumber.org>

[ Upstream commit 77d21f23a1e4db8639e3916547c903a3b3c7a07c ]

Programs using virtio headers outside of kernel will no longer
build because u16 type does not exist in userspace. All user ABI
must use __u16 typedef instead.

Bug introduce by:
commit 986a4f4d452dec004697f667439d27c3fda9c928
Author: Jason Wang <jasowang@redhat.com>
Date: Fri Dec 7 07:04:56 2012 +0000
