From: Po Liu <po.liu@nxp.com> Date: Wed, 24 Jun 2020 17:36:28 +0800 > From: Po Liu <Po.Liu@nxp.com> > > 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. > > Signed-off-by: Po Liu <Po.Liu@nxp.com> Applied.
