Current police offloading support the 'burst'' and 'rate_bytes_ps'. Some hardware own the capability to limit the frame size. If the frame size larger than the setting, the frame would be dropped. For the police action itself already accept the 'mtu' parameter in tc command. But not extend to tc flower offloading. So extend 'mtu' to tc flower offloading.
