vrouter kernel module compilation is failing with the below errors for kernels < 3.3

Adding the below lines in the vr_host_interface.c seems to solve the problem.

#if (LINUX_VERSION_CODE < KERNEL_VERSION(3,3,0))
#include <linux/types.h>
typedef u64 netdev_features_t;
#endif

Because of this error, it is not possible to deploy opencontrail on Ubuntu 12.04 LTS
