3.9-stable review patch. If anyone has any objections, please let me know.

From: stephen hemminger <stephen@xxxxxxxxxxxxxxxxxx>

[ 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.

commit 986a4f4d452dec004697f667439d27c3fda9c928
